Subject: [PATCH AUTOSEL 5.5 04/56] staging: wilc1000: avoid double unlocking of 'wilc->hif_cs' mutex
Date: Thu,  9 Apr 2020 23:47:08 -0400	[thread overview]
Message-ID: <20200410034800.8381-4-sashal@kernel.org> (raw)
In-Reply-To: <20200410034800.8381-1-sashal@kernel.org>

From: Ajay Singh <ajay.kathat@microchip.com>

[ Upstream commit 6c411581caef6e3b2c286871641018364c6db50a ]

Possible double unlocking of 'wilc->hif_cs' mutex was identified by
smatch [1]. Removed the extra call to release_bus() in
wilc_wlan_handle_txq() which was missed in earlier commit fdc2ac1aafc6
("staging: wilc1000: support suspend/resume functionality").
