Subject: [PATCH AUTOSEL 4.4 151/174] mt7601u: fix bbp version check in mt7601u_wait_bbp_ready
Date: Thu, 16 Jan 2020 12:42:28 -0500 [thread overview]
Message-ID: <20200116174251.24326-151-sashal@kernel.org> (raw)
In-Reply-To: <20200116174251.24326-1-sashal@kernel.org>
From: Lorenzo Bianconi <lorenzo@kernel.org>
[ Upstream commit 15e14f76f85f4f0eab3b8146e1cd3c58ce272823 ]
Fix bbp ready check in mt7601u_wait_bbp_ready. The issue is reported by
coverity with the following error:
Logical vs. bitwise operator
The expression's value does not depend on the operands; inadvertent use
of the wrong operator is a likely logic error.
Addresses-Coverity-ID: 1309441 ("Logical vs. bitwise operator")
Fixes: c869f77d6abb ("add mt7601u driver")
