SFF functions have confusing names. Some have sff prefix, some have bmdma, some std, some pci and some none. Unify the naming by... * SFF functions which are common to both BMDMA and non-BMDMA are prefixed with ata_sff_. * SFF functions which are specific to BMDMA are prefixed with ata_bmdma_. * SFF functions which are specific to PCI but apply to both BMDMA and non-BMDMA are prefixed with ata_pci_sff_. * SFF functions which are specific to PCI and BMDMA are prefixed with ata_pci_bmdma_. * Drop generic prefixes from LLD specific routines. For example, bfin_std_dev_select -> bfin_dev_select. The following renames are noteworthy. ata_qc_issue_prot() -> ata_sff_qc_issue() ata_pci_default_filter() -> ata_bmdma_mode_filter() ata_dev_try_classify() -> ata_sff_dev_classify() This rename is in preparation of separating SFF support out of libata core layer. This patch strictly renames functions and doesn't introduce any behavior difference. Signed-off-by: Tejun Heo <htejun@gmail.com>
