Merge tag 'ata-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata
Pull ata updates from Damien Le Moal:
"For this cycle, no big change but many small fixes and code cleanup to
libata, the ahci driver and various pata drivers. In more details:
- Code simplification in pata_platform using
platform_get_mem_or_io(), from Lad.
- Fix read-only arrays declarations as const in pata_atiixp and
pata_pdc202xx_old, from Colin.
- Various cleanups and code simplification in libata-scsi, from me.
- Remove dead code in libata-acpi, from Sergey.
- Skip device scan deboune delay for Marvell 88SE9235 adapters (ahci)
to speedup boot, from Paul.
- Simplify functions declaration and use for functions always
returning 0 in libata-core, from Sergey.
- Non-fatal error fixes and in the pata_hpt366 and pata_hpt3x2n
drivers, from Sergey.
- Various code cleanup in the pata_artop, pata_hpt37x, pata_hpt366,
pata_hpt3x2n, pata_samsung_cf and sata_rcar drivers, from Sergey.
- Some libata-sff and libata-scsi code cleanup (e.g. change functions
to return "bool"), from Sergey.
- Renae ahci_board_mobile to board_ahci_low_power to be more
descriptive of the feature as that is also used on PC and server
AHCI adapters, from Mario.
- Cleanup of OF match tables, from Geert.
- Simplify the pata_pxa driver initialization using
platform_get_irq(), from Minghao"
