The patch titled
sata_promise: cleanups
has been removed from the -mm tree. Its filename was
sata_promise-cleanups.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: sata_promise: cleanups
From: Mikael Pettersson <mikpe@xxxxxxxx>
This patch applies some trivial cleanups to sata_promise:
- repair whitespace damage
- correct comment at board_2057x_pata definition
- pull SATAII TX4 support code out to separate functions
- rename ata_nr to ata_no for consistency with libata's port_no
- remove some init-time debug printks (requested by Jeff)
This patch should cause no behavioural changes, except for the removed
printks.
