Count this as another vote for review, please -- I have a similar
patch[1] that I would prefer to drop.

This patch does not work for me. Before, the first time after each boot
that I tried to connect to an Apple Magic Mouse, it failed with -14
(EFAULT). With this patch, it fails with -22 (EINVAL) instead. The
-EFAULT *was* due to hidp_parse()'s copy_from_user(). I have not looked
yet to see where the -EINVAL is coming from -- would that help? (Both
with and without your patch, the second attempt to connect works.)
