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. v2 -> v3: - move the new sysfs function into gpiolib-sysfs.c 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 | 45 +++++------ drivers/gpio/gpiolib-sysfs.h | 6 ++ drivers/gpio/gpiolib.c | 143 ++++++++++++++++------------------- drivers/gpio/gpiolib.h | 2 + 4 files changed, 93 insertions(+), 103 deletions(-) -- 2.40.1
