Subject: [PATCH] char: pcmcia: remove set but not used variable 'uc'
Date: Fri, 14 May 2021 14:21:31 +0800 [thread overview]
Message-ID: <20210514062131.3533460-1-yukuai3@huawei.com> (raw)
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/char/pcmcia/cm4040_cs.c:224:16: warning: variable ‘uc’
set but not used [-Wunused-but-set-variable]
It is never used and so can be removed.
Fixes: 77c44ab1d8e9 ("[PATCH] New Omnikey Cardman 4040 driver")
Signed-off-by: Yu Kuai <yukuai3@huawei.com>
