[ACPI] [PATHC] Relaxed syntax for the processor PBLK length

[Eric P. <Eri...@tr...>]

Hello,

In the original DSDT of my laptop (Acer TravelMate 614) the processor 
PBLK length is declared to be 5. The legal and only allowed value is 6. 
This is an error in the DSDT and actually it is 6. Allowing Linux ACPI 
to read also processor PBLK length of 5 works and permits the processor 
to have the C-states correctly detected. In turn it allows the processor 
to get less hot (so this is eventually useful).

I've noticed that some other Acer DSDT also have this length 
mis-indicated. The attached patch adds some logic to the ACPI to allow a 
processor PBLK length of 5 when the syntax is relaxed.

Hoping this can be useful,
Eric
