Subject[PATCH] staging: rtl8723bs: core: make array op_class static const, makes object smaller
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the array op_class on the stack but instead make it
static const. Makes the object code smaller by 64 bytes.

Before:
text data bss dec hex filename
93553 7944 5056 106553 1a039 rtl8723bs/core/rtw_mlme_ext.o

After:
text data bss dec hex filename
93425 8008 5056 106489 19ff9 rtl8723bs/core/rtw_mlme_ext.o

(gcc version 9.2.1, amd64)
