When support for PCC Opregion was added, validation of field_obj was missed. Based on the acpi_ev_address_space_dispatch function description, field_obj can be NULL, and also when acpi_ev_address_space_dispatch is called in the acpi_ex_region_read() NULL is passed as field_obj.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
LGTM, please submit this to ACPICA project as specified in the documentation if not already done. Otherwise a reference to the merge request there would be good here.
