Subject: [PATCH AUTOSEL 4.14 1/5] ASoC: ops: Fix off by one in range control validation
Date: Thu, 14 Jul 2022 00:26:48 -0400 [thread overview]
Message-ID: <20220714042653.282599-1-sashal@kernel.org> (raw)
From: Mark Brown <broonie@kernel.org>
[ Upstream commit 5871321fb4558c55bf9567052b618ff0be6b975e ]
We currently report that range controls accept a range of 0..(max-min) but
accept writes in the range 0..(max-min+1). Remove that extra +1.
