From 5d481e0742dde0d94e3facc39a243ed50c6ce948 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 14 Feb 2024 10:32:48 +0100 Subject: [PATCH] pwm: stm32-lp: Make use of devm_pwmchip_alloc() function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This prepares the pwm-stm32-lp driver to further changes of the pwm core outlined in the commit introducing devm_pwmchip_alloc(). There is no intended semantical change and the driver should behave as before.
