Subject: [patch] [media] as102: remove some unneeded checks
Date: Mon, 22 Sep 2014 10:58:53 +0300 [thread overview]
Message-ID: <20140922075853.GA12362@mwanda> (raw)
We know "ret" is zero so we don't need to test for it. It upsets the
static checkers when we test stuff but we know the answer.
drivers/media/usb/as102/as102_usb_drv.c:164 as102_send_ep1() warn: we tested 'ret' before and it was 'false'
drivers/media/usb/as102/as102_usb_drv.c:189 as102_read_ep2() warn: we tested 'ret' before and it was 'false'
Also, we don't need to initialize "ret".
