Subject: [PATCH 26/28] blk_end_request: changing ide-cd (take 3)
This patch converts ide-cd (cdrom_newpc_intr()) to use blk_end_request
interfaces.
In PIO mode, ide-cd (cdrom_newpc_intr()) needs to defer
end_that_request_last() until the device clears DRQ_STAT and raises
an interrupt

[PATCH] ide-cd: remove dead post_transform_command()
post_transform_command() call in cdrom_newpc_intr() has no effect because
it is done after the request has already been fully completed (rq-bio and
rq-data are always NULL). It was verified to be true
().
As a result, one callback function for DMA mode has been removed.
What do you think about the patch below?

Needs to:

2. wait completing request until DRQ_STAT
