Commit a124820de5fd ("usb: isp1760: fix possible deadlock in
isp1760_udc_irq") replaced spin_{un,}lock with
spin_{un,}lock_irq{save,restore}. However it missed an error path resulting
in the smatch warning as below:

drivers/usb/isp1760/isp1760-udc.c:1230 isp1760_udc_start() warn:
inconsistent returns 'irqsave:flags'. Locked on:   line 1207
Unlocked on: line 1199

This patch fixes the spin unlock in the error path in isp1760_udc_start
thereby removing the smatch warning mentioned above.

Hi Laurent, Felipe,

I am extremely sorry for missing this in my original patch.

I hope you will be ashamed for the 7 generations to come for this totally
unacceptable low quality standard.


Yes ;)

Regards,
Sudeep
