[PATCH v4 09/13] phy: usb: fix driver to defer on clk_get defer

From: Al Cooper <alcooperx@gmail.com>
Date: 2020-01-03 18:19:44
Also in: linux-devicetree, lkml
Subsystem: broadcom brcmstb usb2 and usb3 phy driver, generic phy framework, the rest · Maintainers: Justin Chen, Al Cooper, Vinod Koul, Linus Torvalds

Handle defer on clk_get because the new SCMI clock driver comes
up after this driver.
