Subject: [PATCH 3/10] ACPI / scan: drop IDs that do not comply with the ACPI PNP ID rule
Date: Fri, 30 May 2014 04:24:04 +0200	[thread overview]
Message-ID: <1545244.LmV7JB6kqf@vostro.rjw.lan> (raw)
In-Reply-To: <35042328.kk6ZUUdfyN@vostro.rjw.lan>

From: Zhang Rui <rui.zhang@intel.com>

The PNP ACPI scan handler device ID list includes all the IDs from
all of the struct pnp_device_id instances in the tree, but some of
them do not follow the ACPI PNP ID rule (3 letters + 4 hex digits).

For those IDs, the coressponding devices will never be enumerated
via ACPI, so it is safe to remove them from the PNP ACPI ID list.
