It appears you forgot to fix scc_std_softreset() and one of its callsites
in scc_bdma_stop(). A complete patch is attempted below -- please review.
[PATCH -mm] pata_scc: Keep up with libata core API changes
Little fixlets, that the build started erroring / warning about:
drivers/ata/pata_scc.c: In function 'scc_bmdma_status':
drivers/ata/pata_scc.c:734: error: structure has no member named 'active_tag'
drivers/ata/pata_scc.c: In function 'scc_pata_prereset':
drivers/ata/pata_scc.c:866: warning: passing arg 1 of 'ata_std_prereset' from
incompatible pointer type
drivers/ata/pata_scc.c: In function 'scc_error_handler':
drivers/ata/pata_scc.c:908: warning: passing arg 2 of 'ata_bmdma_drive_eh' from
incompatible pointer type
drivers/ata/pata_scc.c:908: warning: passing arg 3 of 'ata_bmdma_drive_eh' from
incompatible pointer type
drivers/ata/pata_scc.c:908: warning: passing arg 5 of 'ata_bmdma_drive_eh' from
incompatible pointer type
