drivers/net/wireless/rtlwifi/usb.c: In function ‘_usb_read_sync’:
drivers/net/wireless/rtlwifi/usb.c:102:6: warning: ‘status’ may be used uninitialized in this function
drivers/net/wireless/rtlwifi/usb.c:102:6: note: ‘status’ was declared here
My compiler is dumb, but better to eliminate the warning then to have
anyone waste time evaluating this again...
