From b5194c22585d1f3869b2126a87dabecb5ef2627e Mon Sep 17 00:00:00 2001 From: John Keeping Date: Tue, 6 Dec 2022 12:48:55 +0000 Subject: [PATCH] phy: rockchip: handle clock without enable function If a clock doesn't supply the enable hook, clk_enable() will return -ENOSYS. In this case the clock is always enabled so there is no error and the phy initialisation should continue.
