Subject: [PATCH 6/8] pwm: Make pwmchip_[sg]et_drvdata() a wrapper around dev_set_drvdata()
Date: Sun, 17 Mar 2024 11:40:37 +0100	[thread overview]
Message-ID: <a5e05bd2d83421a26fdef6a87d69253c0f98becf.1710670958.git.u.kleine-koenig@pengutronix.de> (raw)
In-Reply-To: <cover.1710670958.git.u.kleine-koenig@pengutronix.de>

Now that a pwm_chip has a dedicated struct device, pwmchip_set_drvdata()
and pwmchip_get_drvdata() can be made thin wrappers around
dev_set_drvdata() and dev_get_drvdata() respectively and the previously
needed pointer can be dropped from struct pwm_chip.
