2019-08-18iio: imu: adis16460: fix variable signednessAlexandru Ardelean
Caught via static-analysis checker: ``` drivers/iio/imu/adis16460.c 152 static int adis16460_set_freq(struct iio_dev *indio_dev, int val, int val2) 153 { 154 struct adis16460 *st = iio_priv(indio_dev); 155 unsigned int t; ^^^^^^^^^^^^^^ 156 157 t = val * 1000 + val2 / 1000; 158 if (t <= 0) ^^^^^^ Unsigned is not less than zero. ``` The types of `val` && `val2` are obtained from the IIO `write_raw` hook, so userspace can provide negative values, which can cause weird behavior after conversion to unsigned. This patch changes the sign of variable `t` so that -EINVAL will be returned for negative values as well.

2019-08-18iio: accel: kxcjk1013: Improve comments on KIOX010A and KIOX020A ACPI idsHans de Goede
The KIOX010A and KIOX020A ACPI ids go hand in hand, they are used in yoga style 2-in-1s, with KIOX010A indicating the KXCJ91008 sensor in the display of the 2-in-1 and KIOX020A indicating the KXCJ91008 sensor in the base. Improve the existing comment on the "KIOX010A" kx_acpi_match table entry to make clear we are talking about a yoga-style (360 degree hinges) device here and add a similar comment to the "KIOX020A" entry.

2019-08-15staging: sm750fb: fix odd license textGreg Kroah-Hartman
There is some "confusing" license text in some of the sm750fb driver files. After discussing it with the company, it turns out to have been a mistake and these lines can be safely removed. The files are all to be licensed under the GPLv2 license.

Done from immutable branch. A counter subsystem patche in here as well. Alongside the new device support (which is always good), Chuhong's work on using devres managed APIs has cleaned up a number of drivers. New device support * adis16460 - New driver based on ADIS framework which needed addition of support for cs_change_delay. Includes device tree binding. * cros_ec - Support fo the veyron-minnie which uses an older interface. * lsm6dsx - Support for LSM6DSTR-C gyro + magnetometer sensor (new IDs mainly) - Support for ISM330DHCX acc + gyro sensor (extensive rework needed!) * Maxim 5432 - New driver support MAX5432-MAX5435 family of potentiometers. * noa1305 - New driver for this ON Semiconductor Ambient light sensor. Features and cleanups * tree wide - Drop error prints after platform_get_irq as already prints errors internally if any occur. * docs - Document mounting matrix. - Fix a missing newline at end of file. * ad2s1210 - Switch to device managed APIs for all of probe and drop explicit remove. * ad7192 - Add of_device_id array to explicity handling DT bindings. * ad7606 - Lots of rework leading to support for software configure modes in ad7616 parts. - Debugfs register access support. * am2315 - Switch to device managed APIs for all of probe and drop explicit remove. * apds9960 - Typo in module description. * cm36651 - Convert to i2c_new_dummy_device. - Swithc to device managed APIs for all of probe adn drop explicit remove. * cros_ec - Calibscale support for accel, gyro and magnetometer. - Tidy up some error codes to return the error from the stack rather than -EIO. - Determine protocol version. - Add a sign vector to the core to fix sensor rotation if necessary. Cannot just be done with mount matrix as already in use in many devices. - Tidy up INFO_SCALE being in both the separate and shared lists. - Drop a lot of dplicate code from the cros-ec-accel-legacy driver and use the core provided code instead. - Make frequency range available to userspace. * counter / ftm-quaddec - Switch to device managed APIs for all of probe adn drop explicit remove. * hdc100x - Switch to device managed APIs for all of probe and drop explicit remove. * hi8435 - Use gpiod_set_value_cansleep as we don't care here and there is a board out there where it needs to sleep. - Switch to device managed APIs for all of probe and drop explict remove. * hp03 - Convert to i2c_new_dummy_device. * maxim thermocouple - Switch to device managed APIs for all of probe and drop explicit remove. * mmc35240 - Fix typo in constant naming. * mpu6050 - Use devm_add_action_or_reset in place of explicit error handling. - Make text in Kconfig more explicit about which parts are supported. * mxc4005 - Switch to device managed APIs for all of probe and drop explicit remove. * pms7003 - Convert device tree bindings to yaml. - Add a MAINTAINERS entry * sc27xx - Introduce a local struct device *dev pointer to avoid lots of deref. - Use devm_add_action_or_reset in place of explicit error handling. * sca3000 - Typo fix in naming. * si1145 - Switch to device managed APIs for all of probe and drop explicit remove. * st_sensors - Lots of rework to enable switch to regmap. - Regmap conversion at the end. - Tidy up some inconsistencies in buffer setup ops. - Tidy up an oddity by dropping get_irq_data_ready function in favour of direct access. - Stop allocating buffer in buffer enable in favour of just embedding a large enough constant size buffer in the iio_priv accessed structure. * st_lsm6dsx - l3c device support (LSM6DSO and LSM6DSR) - tidy up irq return logic which was strangely written. - fix up an ABI quirk where this driver used separate scale attributes, even though they were always shared by type. * stk33xx - Device tree bindings include manufacturer ID. * stm32-adc - Add control for supply to analog switches including DT bindings. * stm32 timer - Drop the quadrature mode support. Believed there were no users so take this opportunity to drop this unwanted ABI. * tsl2772 - Switch to device mangage APIs for all of probe and drop explicit remove. - Use regulator_bulk_* APIs to reduce repitition. * veml6070 - Convert to i2c_new_dummy_device. * tag 'iio-for-5.4a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (84 commits) iio: hi8435: Drop hi8435_remove() by using devres for remaining elements iio: hi8435: Use gpiod_set_value_cansleep() iio:st_sensors: remove buffer allocation at each buffer enable iio: imu: inv_mpu6050: be more explicit on supported chips iio: light: noa1305: Add support for NOA1305 dt-bindings: Add binding document for NOA1305 iio: remove get_irq_data_ready() function pointer and use IRQ number directly iio: imu: st_lsm6dsx: make IIO_CHAN_INFO_SCALE shared by type iio: tsl2772: Use regulator_bulk_() APIs iio: tsl2772: Use devm_iio_device_register iio: tsl2772: Use devm_add_action_or_reset for tsl2772_chip_off iio: tsl2772: Use devm_add_action_or_reset iio: Remove dev_err() usage after platform_get_irq() iio: light: si1145: Use device-managed APIs iio:pressure: preenable/postenable/predisable fixup for ST press buffer iio:magn: preenable/postenable/predisable fixup for ST magn buffer iio:gyro: preenable/postenable/predisable fixup for ST gyro buffer iio:accel: preenable/postenable/predisable fixup for ST accel buffer dt-bindings: iio: imu: st_lsm6dsx: add ism330dhcx device bindings iio: imu: st_lsm6dsx: add support to ISM330DHCX ...

2019-08-12staging: wilc1000: Don't reset WILC CPU disgracefullyAdham Abozaeid
Send abort request to WILC from wilc_wlan_stop instead of resetting the CPU. The abort request was being sent from wilc_wlan_cleanup after the CPU was reset which wasn't the correct order. The abort request handler in the chip will take care of resetting the CPU.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull dax fixes from Dan Williams: "A filesystem-dax and device-dax fix for v5.3. The filesystem-dax fix is tagged for stable as the implementation has been mistakenly throwing away all cow pages on any truncate or hole punch operation as part of the solution to coordinate device-dma vs truncate to dax pages. The device-dax change fixes up a regression this cycle from the introduction of a common 'internal per-cpu-ref' implementation.

This patch is removing the buffer allocation at each buffer enable. We just allocate enough memory in the main structure during probe to cover maximum size needed (that anyway is pretty small) [16bytes].
