[alsa-devel] [PATCH v1 1/8] lib/uuid: Introduce uuid_{be|le}_cmp_p{p}() helpers

[Winkler, Tomas]

> New helpers take pointers to uuid_{be|le} as parameters.
> 
> When using them on a raw data we don't need to do an ugly dereference and,
> in some cases, a type casting.

I think this going overboard, the _pp types  are just enough.
