Subject: [PATCH 2/7] backlight: l4f00242t03: Simplify with dev_err_probe()
Date: Mon, 04 Mar 2024 11:11:39 +0100	[thread overview]
Message-ID: <20240304-backlight-probe-v1-2-e5f57d0df6e6@linaro.org> (raw)
In-Reply-To: <20240304-backlight-probe-v1-0-e5f57d0df6e6@linaro.org>

Common pattern of handling deferred probe can be simplified with
dev_err_probe().  Less code and also it prints the error value.
