Subject: [PATCH v2 05/13] backlight: qcom-wled: Override default length with qcom,enabled-strings
Date: Thu, 7 Oct 2021 23:33:52 +0200 [thread overview]
Message-ID: <20211007213400.258371-6-marijn.suijten@somainline.org> (raw)
In-Reply-To: <20211007213400.258371-1-marijn.suijten@somainline.org>
The length of qcom,enabled-strings as property array is enough to
determine the number of strings to be enabled, without needing to set
qcom,num-strings to override the default number of strings when less
than the default (which is also the maxium) is provided in DT.
Fixes: 775d2ffb4af6 ("backlight: qcom-wled: Restructure the driver for WLED3")
Signed-off-by: Marijn Suijten <marijn.suijten@somainline.org>
