ATA changes for 5.20-rc1
* 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. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQSRPv8tYSvhwAzJdzjdoc3SxdoYdgUCYuoTcgAKCRDdoc3SxdoY dojoAQCwcthqQZ3BbKvN+VJZhSILGaZTELsll4Dpfb7aIbEJ3QEA7rRbidUnUG9c k6Ef0HHJQz38x2Iwo2sHzi+/IRq03gw= =zur4 -----END PGP SIGNATURE----- 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.
