-stable review patch. If anyone has any objections, please let us know. ------------------
From: Mark Lord <liml@rtr.ca>
Okay, just to sum things up.
This forces libata to wait for up to 2 seconds for BUSY|DRQ to clear on resume before continuing.
[jgarzik adds...] During testing we never saw DRQ asserted, but nonetheless (a) this works and (b) testing for DRQ won't hurt.
