From b1a80d5053f3d94b132642aacfcadc55782d1e65 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 14 Feb 2024 10:31:15 +0100 Subject: [PATCH] pwm: crc: Make use of devm_pwmchip_alloc() function MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This prepares the pwm-crc 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.
