Subject: wifi: rtw88: correct qsel_to_ep[] type as int
From: Ping-Ke Shih <pkshih@xxxxxxxxxxx>
commit 8e4942db5f5ed7b7d9690d93235b3ca49c5c59ce upstream.
qsel_to_ep[] can be assigned negative value, so change type from 'u8' to
'int'. Otherwise, Smatch static checker warns:
drivers/net/wireless/realtek/rtw88/usb.c:219 rtw_usb_parse() warn:
assigning (-22) to unsigned variable 'rtwusb->qsel_to_ep[8]'
