2022-03-18tty: serial: samsung: constify variables and pointersKrzysztof Kozlowski
Constify variables, data pointed by several pointers and "udivslot_table" static array. This makes code a bit safer.

2022-03-18tty: serial: samsung: constify s3c24xx_serial_drv_data membersKrzysztof Kozlowski
The driver data (struct s3c24xx_serial_drv_data) is never modified, so also its members can be made const. Except code style this has no impact because the structure itself is always a const.

2022-03-18tty: serial: samsung: reduce number of castsKrzysztof Kozlowski
The pointers to instances of "struct s3c24xx_serial_drv_data" are first cast to kernel_ulong_t and then either used directly (in "platform_device_id.driver_data") or cast again to void * (in "of_device_id.data"). One cast can be dropped, so at least for "of_device_id.data" case there will be no casts at all. This makes the code a bit simpler.

2022-03-18serial: samsung_tty: do not unlock port->lock for uart_write_wakeup()Jiri Slaby
The commit c15c3747ee32 (serial: samsung: fix potential soft lockup during uart write) added an unlock of port->lock before uart_write_wakeup() and a lock after it. It was always problematic to write data from tty_ldisc_ops::write_wakeup and it was even documented that way. We fixed the line disciplines to conform to this recently. So if there is still a missed one, we should fix them instead of this workaround. On the top of that, s3c24xx_serial_tx_dma_complete() in this driver still holds the port->lock while calling uart_write_wakeup(). So revert the wrap added by the commit above.

2022-03-18USB: usb-storage: Fix use of bitfields for hardware data in ene_ub6250.cAlan Stern
The kernel test robot found a problem with the ene_ub6250 subdriver in usb-storage: It uses structures containing bitfields to represent hardware bits in its SD_STATUS, MS_STATUS, and SM_STATUS bytes. This is not safe; it presumes a particular bit ordering and it assumes the compiler will not insert padding, neither of which is guaranteed. This patch fixes the problem by changing the structures to simple u8 values, with the bitfields replaced by bitmask constants.

https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: First set of new device support, fixes, cleanups and features for IIO in 5.18 This cycle we had quite a few series that applied similar changes to lots of drivers. To keep this description manageable I have called those out in their own section rather than per driver. Particularly pleased to see the long running AFE precision series going in this cycle. Series includes some late breaking fixes. New device support * adi,ada4250 amplifier - New driver and dt bindings for this programmable gain amplifier. * adi,admv1014 microwave down-converter - New driver, dt bindings and some device specific ABI that may be generalized as more drivers for devices similar to this are added. * adi,admv4420 K Band down-converter. - New driver and dt bindings. * adi,adxl367 accelerometer driver. - New driver, dt-bindings + some new IIO ABI definitions to support reference magnitude events where an estimate of the acceleration due to gravity has been removed. - A few fixes as follow up patches. * adi,ltc2688 DAC with toggle and dither modes. - New driver and bindings. Includes some new driver specific (for now) ABI for handling toggle mode and the addition of a dither waveform to the DAC output. * AFE (analog front end) add support for additional types of analog device in front of an ADC. - RTD temperature sensors with dt bindings. - Temperature transducers wit dt bindings. - Related cleanup and features listed in other sections below. * maxim,ds3502 potentiometer. - Add support to ds1803 driver which required significant rework. * mediatek,mt2701-auxadc driver - Add mediatek,mt8186-auxadc - id table and chip specific info only. * semtech,sx9324, semtech,ax9360 - Substantial refactoring of sx9310 to extract core logic for reuse into a separate module - New driver using this supporting sx9324 proximity sensors. - New driver using this supporting sx9360 proximity sensors. * silan,sc7a20 - Compatible with the st,lis2dh (or nearly anyway) so add ID and chip specific info to enable support. Also silan vendor ID added for dt-bindings. Staging graduation * adi,ad7280a monitoring ADC for stacked lithium-ion batteries in electric cars and similar. - Substantial rework of driver required to bring inline with current IIO best practice. An unusual device in IIO so some interesting features we may see more of in future. Multiple driver/core cleanup - Use sysfs_emit() in simple locations where there is no path to change to various core created attributes. - Trivial white space fixes around inconsistency between space after { and before } in id tables. - Introduce new handling for fractional types to avoid repeated similar implementations. Use this in 3 drivers. Note this is also targeted at future use in the AFE driver and was motivated by discussions around the precision related work on that driver. - of related header cleanups - drop of*.h and add mod_devicetable.h as appropriate. - Move a number of symbol exports into IIO_* namespaces. Two categories, 1) Library used by multiple drivers e.g. st_sensors 2) Core driver module exporting functions used by bus specific modules. A few related cleanups in this set. - Switch from CONFIG_PM_* guards to new DEFINE_SIMPLE_DEV_PM_OPS() and similar to simplify drivers and take advantage of these new macros allowing the compiler to do the job or removing unused code without the need for __maybe_unused markings. Conversion of other drivers to these new macros ongoing. Features * adi,adf4350 - Switch from of specific to generic device properties enabling use with other firmware types. * adi,adx345 - Switch from of specific to generic device properties. - Add ACPI ID ADS0345 - Related driver cleanup. * adi,hmc425a - Switch from of specific to generic device properties. * afe analog rescaler driver - Wider range of types supported for scale. - Support offset. - Kunit tests. * atlas,ezo-sensor - Convert from of to device properties. * fsl,mma8452 - Support mount matrix. * infineon,dps310: - Add ACPI ID IFX3100. * invensense,mpu6050 - Convert to generic device properties. * maxim,ds1803 - Add out_raw_available before supporting more devices. - Convert from of specific to device properties. * samsung,ssp_sensors - Convert from of specific to device properties. * st,stm32-timer trigger - Convert from of specific to device properties. * ti,hdc101x - Add ACPI ID TXNW1010. * ti,tsc2046: - Add read_raw support to enable use of iio_hwmon and similar. Fixes / cleanup. * mailmap - Update for Cai Huoqing * MAINTAINERS - Fix Analog Devices related links. - Add entry for ADRF6780 - Add entry for ADMV1013 - Add entry for AD7293 - Add entry for ADMV8818 - Update files listed for adis-lib * iio core: - Fix wrong comment about current_mode being something a driver should ever access. - Use struct_size() rather than open coding in industrialio-hw-consumer * adi,axl355 - Use units.h definitions instead of local versions. * adi,adis-lib - Simplify *updated_bits() macro - Whitespace cleanup. * afe - Note many of these fixes only apply to particular configurations so the problems have probably not been seen in the wild, but will be visible with new usecases enabled this cycle. - Fix application of consumer scale for IIO_VAL_INT. - Apply a scale of 1 when no scale is provided. - Make best effort to establish a valid offset value for fractional cases. - Use s64 for scale calculations where parameters may be signed. - Tidy up include order. - Improve accuracy for small fractional sales - Reduce risk of integer overflow. * ams,as3935 - Use devm_delayed_work_autocancel() to replace open coded equivalent. * aspeed,adc - Fix wrong use of divider flag. * atmel,sama5d2-adc - Relax atmel,trigger-edge-type to optional. - Drop Ludovic Desroches from listed maintainers of the dt-binding inline with previous MAINTAINERS entry update. * fsl,mma8452 - Fix probing when i2c_device_id used. - dev_get_drvdata() on the iio_dev->dev, no longer returns iio_dev. Use dev_to_iio_dev() instead.

2022-03-18platform/x86: think-lmi: Certificate authentication supportMark Pearson
Implementation of certificate authentication feature for Lenovo platforms. This allows for signed updates of BIOS settings. Functionality supported: - Cert support available check. At initialisation check if BIOS supports certification authentication and if a certificate is installed. Enable the sysfs nodes appropriately - certificate and signature authentication attributes to enable a user to install, update and delete a certificate using signed signatures - certificate_thumbprint to confirm installed certificate details - support to go from certificate to password based authentication - signature and save_signature attributes needed for setting BIOS attributes using certificate authentication. Tested on X1 Carbon G10 and X1 Yoga G7. This feature is not generally available yet but will be released later this year. Note, I also cleaned up the formating of the GUIDs when I was adding the new defines. Hope that's OK to combine in this commit.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2022-03-17 1) From Maxim Mikityanskiy, Datapath improvements in preparation for XDP multi buffer This series contains general improvements for the datapath that are useful for the upcoming XDP multi buffer support: a. Non-linear legacy RQ: validate MTU for robustness, build the linear part of SKB over the first hardware fragment (instead of copying the packet headers), adjust headroom calculations to allow enabling headroom in the non-linear mode (useful for XDP multi buffer). b. XDP: do the XDP program test before function call, optimize parameters of mlx5e_xdp_handle. 2) From Rongwei Liu, DR, reduce steering memory usage Currently, mlx5 driver uses mlx5_htbl/chunk/ste to organize steering logic. However there is a little memory waste. This update targets to reduce steering memory footprint by: a. Adjust struct member layout. b. Remove duplicated indicator by using simple functions call. With 500k TX rules(3 ste) plus 500k RX rules(6 stes), these patches can save around 17% memory. 3) Three cleanup commits at the end of this series. =================== Signed-off-by: David S.

2022-03-17hwmon: (pmbus) Add Vin unit off handlingBrandon Wyman
If there is an input undervoltage fault, reported in STATUS_INPUT command response, there is quite likely a "Unit Off For Insufficient Input Voltage" condition as well. Add a constant for bit 3 of STATUS_INPUT. Update the Vin limit attributes to include both bits in the mask for clearing faults. If an input undervoltage fault occurs, causing a unit off for insufficient input voltage, but the unit is off bit is not cleared, the STATUS_WORD will not be updated to clear the input fault condition. Including the unit is off bit (bit 3) allows for the input fault condition to completely clear.

2022-03-18media: Kconfig: cleanup VIDEO_DEV dependenciesMauro Carvalho Chehab
media Kconfig has two entries associated to V4L API: VIDEO_DEV and VIDEO_V4L2. On Kernel 2.6.x, there were two V4L APIs, each one with its own flag. VIDEO_DEV were meant to: 1) enable Video4Linux and make its Kconfig options to appear; 2) it makes the Kernel build the V4L core. while VIDEO_V4L2 where used to distinguish between drivers that implement the newer API and drivers that implemented the former one. With time, such meaning changed, specially after the removal of all V4L version 1 drivers. At the current implementation, VIDEO_DEV only does (1): it enables the media options related to V4L, that now has: menu "Video4Linux options" visible if VIDEO_DEV source "drivers/media/v4l2-core/Kconfig" endmenu but it doesn't affect anymore the V4L core drivers. The rationale is that the V4L2 core has a "soft" dependency at the I2C bus, and now requires to select a number of other Kconfig options: config VIDEO_V4L2 tristate depends on (I2C || I2C=n) && VIDEO_DEV select RATIONAL select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE default (I2C || I2C=n) && VIDEO_DEV In the past, merging them would be tricky, but it seems that it is now possible to merge those symbols, in order to simplify V4L dependencies. Let's keep VIDEO_DEV, as this one is used on some make *defconfig configurations.
