Merge tag 'ata-6.10-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux

Pull ata fixes from Niklas Cassel:

 - Add NOLPM quirk for for all Crucial BX SSD1 models.

   Considering that we now have had bug reports for 3 different BX SSD1
   variants from Crucial with the same product name, make the quirk more
   inclusive, to catch more device models from the same generation.

 - Fix a trivial NULL pointer dereference in the error path for
   ata_host_release().

 - Create a ata_port_free(), so that we don't miss freeing ata_port
   struct members when freeing a struct ata_port.

 - Fix a trivial double free in the error path for ata_host_alloc().

 - Ensure that we remove the libata "remapped NVMe device count" sysfs
   entry on .probe() error.
