[PATCH 3/5] of: module: Mutate of_device_uevent_modalias() into two helpers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Let's move the logic of the former helper into module.c and use it from
an inline helper located under of_device.c. This way there is no change
for users while the logic gets moved to an OF-only file.
