Subject: [RESEND][PATCH v3][next] backlight: sky81452-backlight: Remove unnecessary call to of_node_get
Date: Thu, 2 May 2024 22:51:21 +0530 [thread overview]
Message-ID: <20240502172121.8695-2-shresthprasad7@gmail.com> (raw)
`dev->of_node` already has a reference to the device_node and calling
of_node_get on it is unnecessary. All conresponding calls to
of_node_put are also removed.
Reviewed-by: Daniel Thompson <daniel.thompson@linaro.org>
