Subject: USB: fix PTR_ERR translation in init_usb_class()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=de5535f5f508466cd5796d4e14ad4f301ff86a26;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

USB: fix PTR_ERR translation in init_usb_class()

There is a misprint in init_usb_class():
IS_ERR is used to get error code instead of PTR_ERR.

Found by Linux Driver Verification project (linuxtesting.org).
