From 9a6ac822a2153d583b0da95b8693e954b5f4203a Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Wed, 19 Jul 2023 21:20:12 +0200 Subject: pwm: atmel-tcb: Unroll atmel_tcb_pwm_set_polarity() into only caller MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit atmel_tcb_pwm_set_polarity() is only called once and effectively wraps an assignment only. Replace the function call by the respective assignment.
