Subject: [PATCH] staging: r8188eu: remove useless check
Date: Sun, 5 Sep 2021 23:42:18 +0300 [thread overview]
Message-ID: <20210905204218.19317-1-paskripkin@gmail.com> (raw)
smatch says:
usb_intf.c:326 rtw_hw_suspend() warn: variable dereferenced before check 'padapter' (see line 323)
usb_intf.c:387 rtw_hw_resume() warn: variable dereferenced before check 'padapter' (see line 385)
There is only one caller of rtw_hw_suspend() and it does not check
padapter pointer, so let's just omit this check to make smatch happy.
