[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Adrian Hunter <adrian.hunter@xxxxxxxxx>

This patch has been added to the 3.18 stable tree. If you have any
objections, please let us know.

===============

[ Upstream commit 265984b36ce82fec67957d452dd2b22e010611e4 ]

The CMD19/CMD14 bus width test has been found to be unreliable in
some cases.  It is not essential, so simply remove it.
