HID: uhid: silence gcc warning
gcc is giving me: drivers/hid/uhid.c: In function ‘uhid_hid_get_raw’: drivers/hid/uhid.c:157: warning: ‘len’ may be used uninitialized in this function which is clearly bogus, as - when used as memcpy() argument, it's initialized properly - the code is structured in a way that either 'ret' or 'len' is always initialized, so the return statement always has an initialized value.
