Subject: [PATCH] ASoC: samsung: i2s: Check before clk_unregister() not needed
Date: Thu, 26 May 2022 23:54:12 -0700	[thread overview]
Message-ID: <20220527065412.3677-1-hanyihao@vivo.com> (raw)

clk_unregister() already checks the clk ptr using
!clk || WARN_ON_ONCE(IS_ERR(clk)) so there is no need to check it
again before calling it.
