[PATCH] HID: hiddev: fix returned errno code in hiddev_connect()

[Luis de Bethencourt]

The driver is using -1 instead of the -ENOMEM defined macro to specify
that a buffer allocation failed. Since the error number is propagated,
the caller will get a -EPERM which is the wrong error condition.

Also, the smatch tool complains with the following warning:
hiddev_connect() warn: returning -1 instead of -ENOMEM is sloppy
