From 14ac9e17f9bd4bd0dfe18e384a3c2ca8dfbffcc8 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 7 Jul 2021 18:28:00 +0200 Subject: [PATCH] pwm: ab8500: Simplify using devm_pwmchip_add() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This allows to drop the platform_driver's remove function. This is the only user of driver data so this can go away, too.
