- libata-dont-whine-if-prereset-returns-enoent.patch removed from -mm tree

[akpm]

The patch titled
     libata: don't whine if ->prereset() returns -ENOENT
has been removed from the -mm tree.  Its filename was
     libata-dont-whine-if-prereset-returns-enoent.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
Subject: libata: don't whine if ->prereset() returns -ENOENT
From: Tejun Heo <htejun@gmail.com>

->prereset() returns -ENOENT to tell libata that the port is empty and
reset sequencing should be stopped.  This is not an error condition.
Update ata_eh_reset() such that it sets device classes to ATA_DEV_NONE
and return success in on -ENOENT.  This makes spurious error message
go away.

1.  I think these ports should be made dummy instead of returning
   -ENOENT on prereset().  -ENOENT from prereset() was a hack to keep
   ata_piix's behavior unchanged while converting it to new EH.  If no one
   objcts, I'll convert similar usages to use dummy ports after new init
   model and drop -ENOENT hack in #upstream.

2.  -ENODEV sounds more appropriate.  Why have I used -ENOENT.  :-)
