[PATCH v1 1/4] backlight: hx8357: Make use of device properties

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

 



Convert the module to be property provider agnostic and allow
it to be used on non-OF platforms.

Include mod_devicetable.h explicitly to replace the dropped of.h
which included mod_devicetable.h indirectly.
