Subject: usb: gadget: s3c2410_udc: use platform ids instead
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=513385a3cf97e9fb7e982afffeb013a12a7ccbd2;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

usb: gadget: s3c2410_udc: use platform ids instead

This also fixes the error path: If the second device fails to register
we never remove the first one.
This is compile-tested only. I don't see any difference between those
two. Maybe we should just use one name instead?
