This small patch set fixes a system hang which occurs upon traversal of /sys.
The problem is specific to the particular Marvell controller, as is this
quirk-fix.  A more general fix is in the works upstream, but lets carry this
fix in the meantime.

Identical SRU requests for Quantal and Precise to follow.

This is isolated to one particular device, so risk of regression to 
other devices is limited.  Apparently upstream will be working on a 
different solution, but this may be a larger back-porting exercise for 
later and perhaps maybe too big a change for it to be SRU'd.

This is not upstream; would be useful to reference the origin / 
provenance of these patches.
