[PATCH 0/6] ide: more unifications of ATA and ATAPI support

[Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>]

After this patchset we have a valid struct ide_cmd available also for
ATA_CMD_PACKET commands and comparing struct ide_atapi_pc with ide_cmd it
seems that there are many similarities between them and that we may just
merge both structs (this should also allow us to unify ide-cd code with
non-ide-cd one in ide-atapi.c later).  From the quick look the only gotcha
is REQUEST SENSE handling, ->request_sense_pc needs to be converted to
->request_sense_cmd and we have to be careful with choosing right 'cmd'
in *_issue_pc()...

Borislav, please take a look and tell me what do you think about it
(also feel free to go ahead with patches :-)...
