Merge tag 'ata-5.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata

Pull ATA updates from Damien Le Moal:

 - Some code refactoring for the pata_hpt37x and pata_hpt3x2n drivers,
   from Sergei.

 - Several patches to cleanup in libata-core, libata-scsi and libata-eh
   code: fixes arguments and variables types, change some functions
   declaration to static and fix for a typo in a comment. From Sergey
   and Xiang.

 - Fix a compilation warning in the pata_macio driver, from me.

 - A fix for the expected number of resources in the sata_mv driver fix,
   from Andrew.
