Merge tag 'ata-5.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata
Pull ATA fixes from Damien Le Moal: - Sergey volunteered to be a reviewer for the Renesas R-Car SATA driver and PATA drivers. Update the MAINTAINERS file accordingly. - Regression fix: add a horkage flag to prevent accessing the log directory log page with SATADOM-ML 3ME SATA devices as they react badly to reading that log page (from Anton). * tag 'ata-5.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata: ata: libata-core: Introduce ATA_HORKAGE_NO_LOG_DIR horkage MAINTAINERS: add myself as Renesas R-Car SATA driver reviewer MAINTAINERS: add myself as PATA drivers reviewer
