| |
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)
