Hi Guys,


Bx/Cx: git revert of ed8303fc111e58530e22bd29b0d7e08dced75999

From my own testing, in 2.6.35 (and 2.6.34) the pin write-protect seems busted on the mmc, even with these two patches it doesn't actually detect when the sd card has the write protect enabled.. But atleast they are write-enabled now..

The fix for this bug was posted already at linux-omap (at least no other since the version 6 of the patch set :-), and I can confirm that it fix this issue.

Lee, I know the patch series is not applied yet at linux-omap, but I believe the quality is now OK (it got an ack from Jarkko Nikula, Do you think we can get it applied at our tree?

For testing purposes I added them to my ubuntu kernel tree (;a=shortlog;h=refs/heads/rsalveti-master), and generated the deb I'm using it since last week (at my b5, c4 and xM) and it seems to be working fine.
