Hi Ulf,
In struct mmc_host, there was added a bit definition
'MMC_CAP2_SD_UHS2'(bit 9 of caps2).
But there was already a definition 'MMC_CAP_UHS2'(bit 26 of caps).
Do these two bit definitions work for the same purpose?
By the way, where can I find the 2 source
codes(a/include/linux/mmc/ and b/include/linux/mmc/) which you diff
from.
