[ Upstream commit ef41937631bfee855e2b406e1d536efdaa9ce512 ]
There are thousands of warnings in a W=2 build from just one file:
drivers/net/wireless/realtek/rtlwifi/rtl8821ae/table.c:3788:15: warning: pointer targets in initialization of 'u8 *' {aka 'unsigned char *'} from 'char *' differ in signedness [-Wpointer-sign]
Change the types to consistently use 'const char *' for the strings.
