Subject: ATA/IDE: fix platform driver hotplug/coldplug
X-Git-Tag: v2.6.26-rc1~1060^2~17
X-Git-Url: http://www.pilppa.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=458622fcdc5b316de8d74efd7e610803f0308c14;p=linux-2.6-omap-h63xx.git

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...
