[Intel-gfx] [PATCH 4/5] xvmc: Silence gcc, adding a cast to work around signedness issues.

[Cyril Brulebois]

Both exported XvMCPutSlice/XvMCPutSlice2 functions have a prototype with a
parameter whose signedness differs from the one in the put_slice/put_slice2
functions they call. Make it unsigned through a cast.

Get rid of this accordingly with CFLAGS="-Wall -Werror":
|   CC     intel_xvmc.lo
| cc1: warnings being treated as errors
| intel_xvmc.c: In function ‘XvMCSyncSurface’:
| intel_xvmc.c:677: error: ‘ret’ may be used uninitialized in this function
| intel_xvmc.c:672: note: ‘ret’ was declared here
