The intel_pmc_ipc driver has a placeholder for all possible resources that may have been provided by ACPI. Since there are few optional ones, the driver still uses them and binds to wrong ranges in resource tree: # grep intel_punit_ipc /proc/iomem 00000000-00000000 : intel_punit_ipc 00000000-00000000 : intel_punit_ipc 00000000-00000000 : intel_punit_ipc 00000000-00000000 : intel_punit_ipc This leads to issues with resource management during inserting and removing modules, such as intel_pmc_ipc itself, which can't be inserted anymore after first removal. Count the actual resources provided and supply only them to the child device. This is a real fix of the commit 8cc7fb4a ("intel_pmc_ipc: update acpi resource structure for Punit") that also fixes a symptoms described in the commit 6cc8cbbc ("platform/x86: intel_punit_ipc: Fix resource ioremap warning") that is going to be reverted afterwards.
