From: Paul Mundt <[EMAIL PROTECTED]>
Currently when registration fails we're left with a stray reference to
release_mem_region(), this leads to the following case:
r8a66597_hcd r8a66597_hcd: irq 13, io base 0x18040000
drivers/usb/host/r8a66597-hcd.c: register access fail.
r8a66597_hcd r8a66597_hcd: startup error -6
r8a66597_hcd r8a66597_hcd: USB bus 1 deregistered
drivers/usb/host/r8a66597-hcd.c: Failed to add hcd
Trying to free nonexistent resource <0000000018040000-0000000018040000>
This fixes it up.
