Subject[PATCH, trivial] PNP: Use constant PNP_ID_LEN instead of literal number
The attached patch uses the constant PNP_ID_LEN instead of using a 
literal number for the length of a PNP ID in the scope of PNP quirks.

As a consequence, all IDs used in PNP quirks (c.f. "drivers/pnp/quirks.c")
are now zero-terminated and standard functions that depend on the IDs
to be zero-terminated now work reliably (c.f. "strlen" in "drivers/pnp/driver.c",
function "compare_pnp_id").


The patch is applied against 3.1.
