[Bug Report] Wrong value of __NR_userfaultfd in asm-generic/unistd.h

Hi, The asm-generic/unistd.h file has wrong __NR_userfaultfd syscall number which doesn't even depend on the architecture. This has caused failure of a selftest which was fixed recently [1]. grep -rnIF "#define __NR_userfaultfd" tools/include/uapi/asm-generic/unistd.h:681:#define __NR_userfaultf

[PATCH v2 04/13] media: i2c: imx214: Convert to CCI register access helpers

From: André Apitzsch Use the new common CCI register access helpers to replace the private register access helpers in the imx214 driver. This simplifies the driver by reducing the amount of code. Acked-by: Ricardo Ribalda Signed-off-by: André Apitzsch --- drivers/media/i2c/Kconfig | 1 + d

[PATCH v2 02/13] media: i2c: imx214: Use subdev active state

From: André Apitzsch Port the imx214 sensor driver to use the subdev active state. Move all the format configuration to the subdevice state and simplify the format handling, locking and initialization. While at it, simplify imx214_start_streaming() by removing unneeded goto statements and the c

[PATCH v2 01/13] media: i2c: imx214: Fix link frequency
