Re: [PATCH] HID: uhid: silence gcc warning

Hi Jiri

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.

David,

I have applied this on top of your uhid series in my tree.

Yes, looks totally bogus to me, too. I also don't get the warning with
gcc-4.7.0. Thanks for applying it, looks ok to me.

Regards
David
