Subject: usb: musb: omap2430: fix PHY error handling
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a90199bb947856c24d7bf78845d24f802e09db0a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

usb: musb: omap2430: fix PHY error handling

PHY layer no longer returns NULL. It will
return -ENXIO when PHY layer isn't enabled
and we can use that to bail out instead of
request a probe deferral.
