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.
