Subject: USB: ehci-au1xxx: fix suspend callback
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a7535ac05443f234b9c68389fc053976383feca4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

USB: ehci-au1xxx: fix suspend callback

Remove a stray 'return 0' at the top of the suspend callback,
and move au1xxx_stop_ehc() out of the ehci spinlock since it takes
some time to complete.
