Subject: [PATCH 2/2] drivers/usb/core: devio.c: Removed various warnings and errors generated by checkpatch.pl
Removed warnings and erros from checkpatch.pl that go against the coding style.
Lines 29 and 103: removed unwanted spaces.
Lines 1040 and 1591: changed dev_printk(KERN_DEBUG, ...) to dev_dbg(&dev->dev).
Lines 1942: changed an else switch to else { switch (...) {...} }. (Makes more sense(to me)).
Lines 1319 and 1906: added spaces to fit coding style consistently.
