From f9a8ee8c8bcd118e800d88772c6457381db45224 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Mon, 1 Mar 2021 19:57:19 +0100 Subject: pwm: Always allocate PWM chip base ID dynamically MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since commit 5e5da1e9fbee ("pwm: ab8500: Explicitly allocate pwm chip base dynamically") all drivers use dynamic ID allocation explicitly. New drivers are supposed to do the same, so remove support for driver specified base IDs and drop all assignments in the low-level drivers.
