3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andy Lutomirski <l...@amacapital.net>
commit 812089e01b9f65f90fc8fc670d8cce72a0e01fbb upstream.
Otherwise it fails like this on cards like the Transcend 16GB SDHC card:
mmc0: new SDHC card at address b368
mmcblk0: mmc0:b368 SDC 15.0 GiB
mmcblk0: error -110 sending status command, retrying
mmcblk0: error -84 transferring data, sector 0, nr 8, cmd response 0x900,
card status 0xb0
Tested on my Lenovo x200 laptop.
