From b8f94957765629e6a0d89abb4ff7e06e6565f61f Mon Sep 17 00:00:00 2001 From: Xu Wang Date: Thu, 29 Oct 2020 09:01:04 +0000 Subject: ASoC: pxa: pxa-ssp: Remove redundant null check before clk_prepare_enable/clk_disable_unprepare ecause clk_prepare_enable() and clk_disable_unprepare() already checked NULL clock parameter, so the additional checks are unnecessary, just remove them.
