From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx> I figured that - since the descriptor locking is going to take some more time - we should at least start the conversion and protect the GPIO device list with a mutex. Patch 2/2 here is actually a v2 of the original submission. v1 -> v2: - add a patch renaming two functions - protect the list in gpio_device_find() too - coding style tweaks Bartosz Golaszewski (2): gpiolib: rename static functions that are called with the lock taken gpiolib: use a mutex to protect the list of GPIO devices drivers/gpio/gpiolib-sysfs.c | 26 +----- drivers/gpio/gpiolib-sysfs.h | 6 ++ drivers/gpio/gpiolib.c | 166 ++++++++++++++++++----------------- drivers/gpio/gpiolib.h | 1 - 4 files changed, 94 insertions(+), 105 deletions(-) -- 2.40.1
