From 41d867c9ac852ce17069f8ae680f25877be97942 Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Fri, 18 Apr 2008 13:44:26 -0700 Subject: [PATCH] [MTD] [MAPS] fix platform driver hotplug/coldplug Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable MTD mapping platform drivers, to re-enable auto loading. NOTE oddness with physmap ... it's a legacy driver in some configs, which means it can't always support hotplugging. (Not that most of these mapping drivers would often be used as modules...)
