Subject: [PATCH] HID: hid-gfrm: avoid warning for input_configured API change

The input_configured callback was recently changed to return
an 'int', but the newly added driver uses the old API:

drivers/hid/hid-gfrm.c:151:22: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]

This changes the driver like the other ones.

Hmm, the question is how to merge this, given that one change is in
Jiri's tree and another in mine...

In this case probably the best course of action is you cherry-picking
b2c68a2f1bab from my tree into yours, and proceeding further. git can
handle doubled commits (that will end up in Linus' tree eventually)
easily.

Another option would be to create a joint merge tree that'd contain both
branches merged together and proceed further from that, but I don't think
it's worth the hassle for simple case like this.

Works for you?

Thanks,

I went the cherry-pick route.

Thanks.
