From 22454cb99fc39f2629ad06a7eccb3df312f8830e Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Wed, 28 May 2008 23:06:47 +0200 Subject: [PATCH] pnp: add acpi:* modalias entries Along with the non-modalias conformant "pnp:*" aliases, we add "acpi:*" entries to PNP drivers, to allow module autoloading by ACPI PNP device entries, which export proper modalias information, without any specific userspace modprobe mangling.
