From 3e4224a98b505ea4c6c1ea77ffda0457a7adaacf Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Wed, 14 Feb 2024 10:32:45 +0100 Subject: pwm: stm32-lp: Simplify code to determine the pwmchip's parent device MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is already a pointer to the pwmchip, make use of it directly instead of using the struct stm32_pwm_lp *priv just obtained from it. This also has the advantage of not using struct stm32_pwm_lp::chip any more which will be dropped soon.
