From 4b31eb55dbc64d72ff57a1888f8e4d7996a693bc Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Mon, 17 Feb 2025 11:25:02 +0100 Subject: [PATCH] pwm: Check for CONFIG_PWM using IS_REACHABLE() in main header MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Preparing CONFIG_PWM becoming tristate the right magic to check for the availability of the pwm functions is using IS_REACHABLE() and not IS_ENABLED(). The latter gives the wrong result for built-in code with CONFIG_PWM=m.
