ide_cd_probe() zeroes 'info' prior to calling ide_cdrom_setup() so there is no need to explicitly zero 'info' fields in the latter function. Ditto for fields of CDROM_STATE_FLAGS(), CDROM_CONFIG_FLAGS() and 'cdi' (all are embedded in 'info').

Commit cbb010c1 ide: drop 'initializing' argument from ide_register_hw() * Rename init_hwif_data() to ide_init_port_data() and export it. * For all users of ide_register_hw() with 'initializing' argument set hwif->present and hwif->hold are always zero so convert these host drivers to use ide_find_port()+ide_init_port_data()+ide_init_port_hw() instead (also no need for init_hwif_default() call since the setup done by it gets over-ridden by ide_init_port_hw() call). * Drop 'initializing' argument from ide_register_hw(). introduced the usage of a hwif variable, but forgot to declare the actual variable.

This patch converts ide-cd (cdrom_newpc_intr()) to use blk_end_request interfaces. Related 'uptodate' arguments are converted to 'error'. 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 after end_that_request_first(). So blk_end_request() has to return without completing request even if no leftover in the request. ide-cd uses blk_end_request_callback() and a dummy callback function, which just returns value '1', to tell blk_end_request_callback() about that.

This patch converts "normal" parts of ide to use blk_end_request interfaces. Related 'uptodate' arguments are converted to 'error'. The conversion of 'uptodate' to 'error' is done only for the internal function, __ide_end_request(). ide_end_request() was not changed since it's exported and used by many ide drivers. With this patch, blkdev_dequeue_request() in __ide_end_request() is moved to blk_end_request, since blk_end_request takes care of dequeueing request like below: if (!list_empty(&rq->queuelist)) blkdev_dequeue_request(rq); In the case of ide, o 'dequeue' variable of __ide_end_request() is 1 only when the request is still linked to the queue (i.e. rq->queuelist is not empty) o 'dequeue' variable of __ide_end_request() is 0 only when the request has already been removed from the queue (i.e. rq->queuelist is empty) So blk_end_request can handle it correctly although ide always run thought the code above.

In ide_taskfile_ioctl(), there was a race condition involving drive->io_32bit. It was cleared and restored during ioctl requests but there was no synchronization with other requests. So, other requests could execute with the altered ->io_32bit setting or updated drive->io_32bit could be overwritten by ide_taskfile_ioctl(). This patch adds IDE_TFLAG_IO_16BIT flag to indicate to ide_pio_datablock() that 16-bit I/O is needed regardless of drive->io_32bit settting.
