Subject: [PATCH] staging: rtl8188eu: make two arrays static const, makes object smaller
Git-commit: 0ba4d388d70ed5f6756887ee9184d800110ef23b
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430
Don't populate two arrays on the stack but instead make them
static const. Makes the object code smaller by 49 bytes.
Before: text data bss dec hex filename 26821 5616 0 32437 7eb5 rtl8188eu/core/rtw_ieee80211.o
After: text data bss dec hex filename 26612 5776 0 32388 7e84 rtl8188eu/core/rtw_ieee80211.o
(gcc version 9.2.1, amd64)
