Subject: [PATCH] mfd: wm5102: Mark register 0x19 readable
Date: Mon, 10 Mar 2014 16:29:37 +0000 [thread overview]
Message-ID: <1394468977-23149-1-git-send-email-broonie@kernel.org> (raw)
From: Mark Brown <broonie@linaro.org>
During init the core checks if the wm5102 has finished starting by reading
register 0x19 and looking at the value. This read always fails since this
is not a readable register, mark it as being one.
