From 458622fcdc5b316de8d74efd7e610803f0308c14 Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Fri, 18 Apr 2008 13:41:57 -0700 Subject: [PATCH] ATA/IDE: fix platform driver hotplug/coldplug Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable ATA and IDE platform drivers, to re-enable auto loading. NOTE: both ata/pata_platform.c and ide/legacy/ide_platform.c claim to provide "the" platform_pata driver, and there's no build-time mutual exclusion mechanism. This means that configs which enable both drivers will make some trouble when hotplugging...
