Subject: [PATCH net-next] ieee802154: remove set but not used variable 'status'
Date: Wed, 23 Oct 2019 15:06:18 +0800
Message-ID: <20191023070618.30044-1-yuehaibing@huawei.com> (raw)

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/ieee802154/cc2520.c:221:5: warning:
 variable status set but not used [-Wunused-but-set-variable]

It is never used, so can be removed.
