[PATCH] staging: rtl8723au: os_dep: usb_intf.c: Remove some unused functions

From: Rickard Strandqvist
Date: Wed Dec 17 2014 - 15:34:18 EST


Removes some functions that are not used anywhere:
rtw_hw_resume23a() rtw_hw_suspend23a()

This was partially found by using a static code analysis program called cppcheck.
