2019-03-18ARM: dts: rockchip: Enable WiFi on rk3288-tinkerDavid Summers
This patch adds wifi support to the ASUS Tinker Board (S) machines. This is provided by an wifi card (RTL8723BS) wired into the sdio interface. It requires certain pins pulled, to enable the WiFi. The schematics for these board do not show the WiFi connection, so the connections have been taken from: https://github.com/TinkerBoard/debian_kernel/blob/develop/arch/arm/boot/dts/rk3288-miniarm.dts In particular the pulling of two pins.

2019-03-18staging: comedi: ni_mio_common: Fix divide-by-zero for DIO cmdtestIan Abbott
`ni_cdio_cmdtest()` validates Comedi asynchronous commands for the DIO subdevice (subdevice 2) of supported National Instruments M-series cards. It is called when handling the `COMEDI_CMD` and `COMEDI_CMDTEST` ioctls for this subdevice. There are two causes for a possible divide-by-zero error when validating that the `stop_arg` member of the passed-in command is not too large. The first cause for the divide-by-zero is that calls to `comedi_bytes_per_scan()` are only valid once the command has been copied to `s->async->cmd`, but that copy is only done for the `COMEDI_CMD` ioctl. For the `COMEDI_CMDTEST` ioctl, it will use whatever was left there by the previous `COMEDI_CMD` ioctl, if any. (This is very likely, as it is usual for the application to use `COMEDI_CMDTEST` before `COMEDI_CMD`.) If there has been no previous, valid `COMEDI_CMD` for this subdevice, then `comedi_bytes_per_scan()` will return 0, so the subsequent division in `ni_cdio_cmdtest()` of `s->async->prealloc_bufsz / comedi_bytes_per_scan(s)` will be a divide-by-zero error. To fix this error, call a new function `comedi_bytes_per_scan_cmd(s, cmd)`, based on the existing `comedi_bytes_per_scan(s)` but using a specified `struct comedi_cmd` for its calculations. (Also refactor `comedi_bytes_per_scan()` to call the new function.) Once the first cause for the divide-by-zero has been fixed, the second cause is that `comedi_bytes_per_scan_cmd()` can legitimately return 0 if the `scan_end_arg` member of the `struct comedi_cmd` being tested is 0. Fix it by only performing the division (and validating that `stop_arg` is no more than the maximum value) if `comedi_bytes_per_scan_cmd()` returns a non-zero value.

The ethernet in mt7621 is now supported by drivers/net/ethernet/mediatek/ which provides support for the integrated switch through DSA. This requires some devicetree changes, and particularly allows a board dts to identify which switch ports are present. The second CPU interface - gmac1 - doesn't work yet, so the device tree information may not be correct. The phy (which is present on the gnubee-pc2) can negotiate and report connection speed etc, but no traffic flows. The gnubee-pc1 has two network ports which are 'black' and 'blue'.

2019-03-17IB/mlx5: Use mlx5 core to create/destroy a DEVX DCTYishai Hadas
To prevent a hardware memory leak when a DEVX DCT object is destroyed without calling DRAIN DCT before, (e.g. under cleanup flow), need to manage its creation and destruction via mlx5 core. In that case the DRAIN DCT command will be called and only once that it will be completed the DESTROY DCT command will be called. Otherwise, the DESTROY DCT may fail and a hardware leak may occur. As of that change the DRAIN DCT command should not be exposed any more from DEVX, it's managed internally by the driver to work as expected by the device specification.

2019-03-17xfs: don't trip over uninitialized buffer on extent read of corrupted inodeBrian Foster
We've had rather rare reports of bmap btree block corruption where the bmap root block has a level count of zero. The root cause of the corruption is so far unknown. We do have verifier checks to detect this form of on-disk corruption, but this doesn't cover a memory corruption variant of the problem. The latter is a reasonable possibility because the root block is part of the inode fork and can reside in-core for some time before inode extents are read. If this occurs, it leads to a system crash such as the following: BUG: unable to handle kernel paging request at ffffffff00000221 PF error: [normal kernel read fault] ... RIP: 0010:xfs_trans_brelse+0xf/0x200 [xfs] ...

The charlcd driver currently flashes the backlight once on init. This may not be desirable. Thus, add options for turning the backlight off or on as well. Signed-off-by: Mans Rullgard <mans@mansr.com> Signed-off-by: Miguel Ojeda <miguel.ojeda.sandonis@gmail.com>

If CONFIG_PANEL_CHANGE_MESSAGE is set, CONFIG_PANEL_BOOT_MESSAGE will also be defined, so the double ifdef is pointless. Simplify the code further by using an intermediate macro rather duplicating most of the line.

2019-03-17auxdisplay: deconfuse configurationMans Rullgard
The auxdisplay Kconfig is confusing. It creates two separate menus even though the settings are closely related. Moreover, the options for setting the boot message depend on CONFIG_PARPORT even though they are used by drivers that do not. Clear up the confusion by moving the "Parallel port LCD/Keypad" menu under auxdisplay where it logically belongs. Change the boot message options to depend only on CONFIG_CHARLCD, making them accessible also when only the HD44780 is selected. Since the "Parallel port LCD/Keypad" driver now has a new dependency on CONFIG_AUXDISPLAY, rename its Kconfig symbol and keep the old one such that make oldconfig will not disable the driver.

2019-03-17ALSA: firewire-motu: use 'version' field of unit directory to identify modelTakashi Sakamoto
Current ALSA firewire-motu driver uses the value of 'model' field of unit directory in configuration ROM for modalias for MOTU FireWire models. However, as long as I checked, Pre8 and 828mk3(Hybrid) have the same value for the field (=0x100800). unit | version | model --------------- | --------- | ---------- 828mkII | 0x000003 | 0x101800 Traveler | 0x000009 | 0x107800 Pre8 | 0x00000f | 0x100800 <- 828mk3(FW) | 0x000015 | 0x106800 AudioExpress | 0x000033 | 0x104800 828mk3(Hybrid) | 0x000035 | 0x100800 <- When updating firmware for MOTU 8pre FireWire from v1.0.0 to v1.0.3, I got change of the value from 0x100800 to 0x103800. On the other hand, the value of 'version' field is fixed to 0x00000f. As a quick glance, the higher 12 bits of the value of 'version' field represent firmware version, while the lower 12 bits is unknown. By induction, the value of 'version' field represents actual model. This commit changes modalias to match the value of 'version' field, instead of 'model' field. For degug, long name of added sound card includes hexadecimal value of 'model' field.

Currently, every arch/*/include/uapi/asm/Kbuild explicitly includes the common Kbuild.asm file.
