From a2da597ff6f5504fc99163de4f15b7f3a129894e Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 25 Oct 2023 14:57:34 +0300 Subject: pwm: samsung: Fix a bit test in pwm_samsung_resume() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The PWMF_REQUESTED enum is supposed to be used with test_bit() and not used as in a bitwise AND. In this specific code the flag will never be set so the function is effectively a no-op.
