Subject: usb: dwc3: of-simple: Fix warning during unbind
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8d53e626759415700022d421e4e0eab245c2dc23;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

usb: dwc3: of-simple: Fix warning during unbind

In dwc3_of_simple_remove() we are using clk_unprepare() before doing
any clk_disable(). If we enable Common CLK framework (CCF) and try to
unbind dwc3-of-simple driver, we see kernel WARN messages.

This patch fixes this kernel warning by using clk_disable_unprepare()
instead of clk_unprepare().
