ide: keep track of number of bytes instead of sectors in struct ide_cmd
* Pass number of bytes instead of sectors to ide_init_sg_cmd(). * Pass number of bytes to process to ide_pio_sector() and rename it to ide_pio_bytes(). * Rename ->nsect field to ->nbytes in struct ide_cmd and use ->nbytes, ->nleft and ->cursg_ofs to keep track of number of bytes instead of sectors. There should be no functional changes caused by this patch. Acked-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
