The patch titled
pata_optidma: rework for cable detect and to remove post_set_mode()
has been removed from the -mm tree. Its filename was
pata_optidma-rework-for-cable-detect-and-to-remove.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: pata_optidma: rework for cable detect and to remove post_set_mode()
From: Alan Cox <alan@xxxxxxxxxx>
A lot of noise because I had to rename the optidma_set_mode() method to
avoid confusion with the new ->set_mode() method that was added. Cable
detect side is pretty trivial.
