We need to turn regulators on and off when switching brightness, and that may block, therefore we have to set stmfts_brightness_set() as LED's brightness_set_blocking() method.

If the user attempts to update Atmel device with an invalid configuration cfg file, error handling code is trying to free cfg file memory which is not allocated yet hence results into kernel crash. This patch fixes the order of memory free operations.

Some open coded versions of this got removed in drivers. This also enables proper SCCB support in regmap. - locking got a more precise naming. i2c_{un}lock_adapter() had to go, and we know use i2c_lock_bus() consistently with flags like I2C_LOCK_ROOT_ADAPTER and I2C_LOCK_SEGMENT to avoid ambiguity. - the gpio fault injector got a new delicate testcase - the bus recovery procedure got fixed to handle the new testcase correctly - a new quirk flag for controllers not able to handle zero length messages together with driver updates to use it - new drivers: FSI bus attached I2C masters, GENI I2C controller, Owl family S900 - and a good set of driver improvements and bugfixes * 'i2c/for-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (77 commits) i2c: rcar: implement STOP and REP_START according to docs i2c: rcar: refactor private flags i2c: core: ACPI: Make acpi_gsb_i2c_read_bytes() check i2c_transfer return value i2c: core: ACPI: Properly set status byte to 0 for multi-byte writes dt-bindings: i2c: rcar: Add r8a774a1 support dt-bindings: i2c: sh_mobile: Add r8a774a1 support i2c: imx: Simplify stopped state tracking i2c: imx: Fix race condition in dma read i2c: pasemi: remove hardcoded bus numbers on smbus i2c: designware: Add SPDX license tag i2c: designware: Convert to use struct i2c_timings i2c: core: Parse SDA hold time from firmware i2c: designware-pcidrv: Mark expected switch fall-through i2c: amd8111: Mark expected switch fall-through i2c: sh_mobile: use core to detect 'no zero length read' quirk i2c: xlr: use core to detect 'no zero length' quirk i2c: rcar: use core to detect 'no zero length' quirk i2c: stu300: use core to detect 'no zero length' quirk i2c: pmcmsp: use core to detect 'no zero length' quirk i2c: mxs: use core to detect 'no zero length' quirk ... 2018-08-18T23:48:07+00:00 Linus Torvalds torvalds@linux-foundation.org 2018-08-18T23:48:07+00:00 urn:sha1:08b5fa819970c318e58ab638f497633c25971813 Pull input updates from Dmitry Torokhov: - a new driver for Rohm BU21029 touch controller - new bitmap APIs: bitmap_alloc, bitmap_zalloc and bitmap_free - updates to Atmel, eeti. pxrc and iforce drivers - assorted driver cleanups and fixes. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (57 commits) MAINTAINERS: Add PhoenixRC Flight Controller Adapter Input: do not use WARN() in input_alloc_absinfo() Input: mark expected switch fall-throughs Input: raydium_i2c_ts - use true and false for boolean values Input: evdev - switch to bitmap API Input: gpio-keys - switch to bitmap_zalloc() Input: elan_i2c_smbus - cast sizeof to int for comparison bitmap: Add bitmap_alloc(), bitmap_zalloc() and bitmap_free() md: Avoid namespace collision with bitmap API dm: Avoid namespace collision with bitmap API Input: pm8941-pwrkey - add resin entry Input: pm8941-pwrkey - abstract register offsets and event code Input: iforce - reorganize joystick configuration lists Input: atmel_mxt_ts - move completion to after config crc is updated Input: atmel_mxt_ts - don't report zero pressure from T9 Input: atmel_mxt_ts - zero terminate config firmware file Input: atmel_mxt_ts - refactor config update code to add context struct Input: atmel_mxt_ts - config CRC may start at T71 Input: atmel_mxt_ts - remove unnecessary debug on ENOMEM Input: atmel_mxt_ts - remove duplicate setup of ABS_MT_PRESSURE ... 2018-08-16T18:10:56+00:00 Dmitry Torokhov dmitry.torokhov@gmail.com 2018-08-16T18:10:56+00:00 urn:sha1:13fe7056bebb4015c6231a07a1be4d3aebbfe979 Prepare input updates for 4.19 merge window.
