ide: add ->max_sectors field to struct ide_port_info
* Add ->max_sectors field to struct ide_port_info to allow host drivers to specify value used for hwif->rqsize (if smaller than the default). * Convert pdc202xx_old to use ->max_sectors and remove no longer needed IDE_HFLAG_RQSIZE_256 flag. There should be no functional changes caused by this patch. Acked-by: Sergei Shtyltov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
