I sadly missed this patch and it is merged now.
But:
Nacked-by: Hans Verkuil <hans.verkuil@xxxxxxxxx>
This sparse warnings are due to a sparse bug that has been fixed in the sparse
git repo. It's not included in sparse-0.5.0, the fix came in later.
The #define that you kept it the version that does not comply with the C11 spec, so
this is likely to fail with non-gcc compilers (gcc apparently kept support for the
old pre-4.6 syntax).
Regards,
Hans
