Subject: HID: cp2112: fix gpio-callback error handling
From: Johan Hovold <johan@xxxxxxxxxx>
commit 8e9faa15469ed7c7467423db4c62aeed3ff4cae3 upstream.
In case of a zero-length report, the gpio direction_input callback would
currently return success instead of an errno.
Fixes: 1ffb3c40ffb5 ("HID: cp2112: make transfer buffers DMA capable")
