[PATCH 0/2] Proper MMC command classes support
From: Pierre Ossman
Date: Tue May 17 2005 - 17:46:11 EST
The MMC block layer currently contains an if-clause which only seems to
serve the purpose of killing forward compatibility:
if (card->csd.cmdclass & ~0x1ff)
return -ENODEV;
This checks for (what I presume) command classes that were undefined
when this code was written. Since these are now starting to be used,
this code is causing a lot of problems. The following two patches tries
to make a more sane check of the command classes.
(Note. The new command class is for high speed cards to allow higher
transfer rates than normal)
