Merge tag 'pnp-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull PNP updates from Rafael Wysocki:
 "These clean the PNP code somewhat:

   - Remove the now unused pnp_find_card() function (Christoph Hellwig)

   - Drop duplicate pci.h include from the quirks code and add an
     "internal.h" include to acpi_pnp.c to fix a compiler warning (Tian
     Tao)"
