Subject: [PATCH, trivial] PNP: Use constant PNP_ID_LEN instead of literal number
Date: Sun, 27 Nov 2011 22:26:20 +0100 [thread overview]
Message-ID: <20111127212620.268500@gmx.net> (raw)
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.
