Subject: [PATCH] staging: rtl8192u: remove unneeded compiler flags
Git-commit: cd42570fa91c2831a23849c8fc59417557d0292a
Patch-mainline: v5.6-rc1
References: jsc#SLE-13430

-std=gnu89 is specified by the top Makefile. Adding it in a driver
Makefile is redundant.

A driver should avoid specifying the optimization flag.
-O2, -O3, or -Os is passed by the top Makefile based on the
CONFIG_CC_OPTIMIZE_FOR_* option.
