There is a bug, when get_user_pages() failed but partially pinned
pages are not unpinned and positive numbers are returned instead of
-ERRNO. Fixed it.
Also, int is more appropriate type for rv. Changed it.

The code has the functionality to insert the GPIO lines using
the global GPIO numbers through module parameters.
As we are clearly deprecating the use of global GPIO numbers
look up the GPIO descriptors from the device instead. This
usually falls back to device hardware descriptions using e.g.
dev
