Subject: USB: Add more empty functions in otg.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=748eee0986f0d51c7bc39f194d515a8d8248ebdd;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

USB: Add more empty functions in otg.h

Add empty functions for get/put transceiver functions too, so that
drivers that optionally use them can call them without worrying that
they might not exist, eliminating ifdefs.
