Subject: [v2,1/2] usb: host: xhci-plat: Remove useless test before clk_disable_unprepare
Date: Thu, 19 Apr 2018 15:30:52 +0200 [thread overview]
Message-ID: <20180419133053.11894-2-gregory.clement@bootlin.com> (raw)
clk_disable_unprepare() already checks that the clock pointer is valid.
No need to test it before calling it.
