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).
