Merge tag 'ata-5.17-rc4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata
Pull ata fixes from Damien Le Moal:
"A couple of additional fixes for 5.17-rc4:
- Fix compilation warnings in the sata_fsl driver (powerpc) (me)
- Disable TRIM commands on M88V29 devices as these commands are
failing despite the device reporting it supports TRIM (Zoltan)"
