I got warnings and after a quick look they look valid but not sure:
drivers/net/wireless/realtek/rtlwifi/rtl8192ce/sw.c: In function 'rtl92c_init_sw_vars':
drivers/net/wireless/realtek/rtlwifi/rtl8192ce/sw.c:179:6: warning: 'fw_name' may be used uninitialized in this function [-Wuninitialized]

drivers/net/wireless/realtek/rtlwifi/rtl8723ae/sw.c:187:6: warning: 'fw_name' may be used uninitialized in this function [-Wuninitialized]
