Bluetooth: hidp: buffer overflow in hidp_process_report
commit 7992c18810e568b95c869b227137a2215702a805 upstream.
CVE-2018-9363
The buffer length is unsigned at all layers, but gets cast to int and
checked in hidp_process_report and can lead to a buffer overflow.
Switch len parameter to unsigned int to resolve issue.
This affects 3.18 and newer kernels.
