If anyone has any objections, please let me know. ------------------ From: Aaron Ma commit 3064a03b94e60388f0955fcc29f3e8a978d28f75 upstream. Follow the change of return type u32 of hid_report_len, fix all the types of variables those get the return value of hid_report_len to u32, and all other code already uses u32.
