From 4d23359b7ec8b03da2154df935af7d625075f6cf Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 5 Sep 2005 10:35:20 +0200 Subject: [ALSA] sparse address space annotations ALSA Core,RawMidi Midlevel,ALSA<-OSS emulation,ALSA sequencer RME32 driver,RME96 driver,EMU10K1/EMU10K2 driver,NM256 driver Add sparse annotations where we do strange this with __iomem/__user pointers.
