[PATCH 1/2] staging: rtl8723bs: convert private allocation functions to return void *

From: Joe Perches
Date: Sat Sep 09 2017 - 16:15:43 EST


Using char * for a return from allocation functions means the
code has to cast generic allocations to specific types.

Allow the compiler to not need casts on the allocations.
