During commit e252652fb2664d42de19f933aa3688bbc470de3f ("ACPICA:
acpidump: Remove integer types translation protection.") two 'unsigned
char' types got converted to 'u8'.

The result does not compile with gcc-4.5, it can not cope with duplicate
typedefs.

The 2 u8 typedefs actually are different types in ACPICA.
If this really causes problem, I'm OK with deleting it from Linux side.
We'll take care of introducing a new type to eliminate such "divergence".

Thanks

In ACPICA, one u8 is UINT8 and the other is for BOOLEAN.
Pleas merge this first.
I'll think about a solution to reduce this divergence.

Thanks and best regards

Applied, thanks!

Lv, can you please see if that's an upstream issue too?
