Subject: [PATCH] pwm: mediatek: Simplify using devm_pwmchip_add()
Date: Mon, 6 Sep 2021 17:30:30 +0800 [thread overview]
Message-ID: <20210906093030.459-1-long870912@gmail.com> (raw)
With devm_pwmchip_add() we can drop pwmchip_remove() from the device
remove callback. The latter can then go away, too and as this is the
only user of platform_get_drvdata(), the respective call to
platform_set_drvdata() can go, too.
