Subject: [PATCH AUTOSEL 5.15 06/19] ASoC: ops: Validate input values in snd_soc_put_volsw_range()
Date: Tue, 10 May 2022 11:44:16 -0400	[thread overview]
Message-ID: <20220510154429.153677-6-sashal@kernel.org> (raw)
In-Reply-To: <20220510154429.153677-1-sashal@kernel.org>

From: Mark Brown <broonie@kernel.org>

[ Upstream commit aa22125c57f9e577f0a667e4fa07fc3fa8ca1e60 ]

Check that values written via snd_soc_put_volsw_range() are
within the range advertised by the control, ensuring that we
don't write out of spec values to the hardware.
