From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently the assignment of -ENOMEM to error is redudant because error
is not being read and -ENOMEM is being hard coded as an error return.
Fix this by returning the error code in variable 'error'; this also
allows the error code from a failed call to input_register_device to
be preserved and returned to the caller rather than just returning
a possibly inappropriate -ENOMEM.
Kudos to Dan Carpenter for the suggestion of an improved fix.

V2: change subject line and return the error code rather than
removing the ENOMEM assignment to error. Thanks to Dan Carpenter
for explaining a better fix.
