Subject: [PATCH] drivers: staging: media: go7007: go7007-usb.c use pr_*() instead of dev_*() before 'go' initialized in go7007_usb_probe()
Date: Wed, 27 Nov 2013 11:17:22 +0800 [thread overview]
Message-ID: <52956442.50001@gmail.com> (raw)
In-Reply-To: <5294255E.7040105@gmail.com>
dev_*() assumes 'go' is already initialized, so need use pr_*() instead
of before 'go' initialized. Related warning (with allmodconfig under
hexagon):
CC [M] drivers/staging/media/go7007/go7007-usb.o
drivers/staging/media/go7007/go7007-usb.c: In function 'go7007_usb_probe':
drivers/staging/media/go7007/go7007-usb.c:1060:2: warning: 'go' may be used uninitialized in this function [-Wuninitialized]
Also remove useless code after 'return' statement.
