From 27410ee7e391ce650d6d0242805f080599be7ad7 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Tue, 1 May 2012 15:40:15 +0200 Subject: mmc: core: use a more generic name for slot function types and fields struct mmc_host::hotplug is becoming a generic hook for slot functions. Rename it accordingly.
