From 5a7fbe452ad9e4a8988d4c20d7acf148383f8106 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Thu, 17 Nov 2022 08:21:51 +0100 Subject: backlight: pwm_bl: Drop support for legacy PWM probing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is no in-tree user left which relies on legacy probing. So drop support for it which removes another user of the deprecated pwm_request() function.
