From 1fa645b1c92795b090ea8de314b5cecc22dbfb03 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 22 Jul 2020 13:07:46 -0400 Subject: usb: bdc: Use devm_clk_get_optional() The BDC clock is optional and we may get an -EPROBE_DEFER error code which would not be propagated correctly, fix this by using devm_clk_get_optional().
