Pietro Borrello 07bc32e53c HID: betop: check shape of output reports
[ Upstream commit 3782c0d6edf658b71354a64d60aa7a296188fc90 ]

betopff_init() only checks the total sum of the report counts for each
report field to be at least 4, but hid_betopff_play() expects 4 report
fields.
A device advertising an output report with one field and 4 report counts
would pass the check but crash the kernel with a NULL pointer dereference
in hid_betopff_play().
