Merge branches 'acpi-ec', 'acpi-apei' and 'pnp'

Merge ACPI EC driver fixes, an ACPI APEI fix and PNP fixes for
6.10-rc3:

- Fix error handling during EC operation region accesses in the ACPI EC
driver (Armin Wolf).

- Fix a memory leak in the APEI error injection driver introduced
during its converion to a platform driver (Dan Williams).

- Fix build failures related to the dev_is_pnp() macro by redefining it
as a proper function and exporting it to modules as appropriate and
unexport pnp_bus_type which need not be exported any more (Andy
Shevchenko).

* acpi-ec:
ACPI: EC: Avoid returning AE_OK on errors in address space handler
ACPI: EC: Abort address space access upon error

* acpi-apei:
ACPI: APEI: EINJ: Fix einj_dev release leak

* pnp:
PNP: Hide pnp_bus_type from the non-PNP code
PNP: Make dev_is_pnp() to be a function and export it for modules
