From b4f78ff746ec5274fffa92fa2a4dc531360b5016 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Fri, 14 Jul 2023 22:56:14 +0200 Subject: [PATCH] pwm: Use a consistent name for pwm_chip pointers in the core MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Most variables of type struct pwm_chip * are named "chip", there are only three outliers called "pc". Change these three to "chip", too, for consistency.
