Some 'clk_prepare_enable()' and 'clk_get()' must be undone in the error
handling path of the probe function, as already done in the remove
function.

According to https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/usb/gadget/s3c2410_udc.c?id=3fc154b6b8134b98bb94d60cad9a46ec1ffbe372
the commit ID looks correct to me. Maybe something should be tweaked somewhere
before applying, but I don't know what!
