- Update the realtek-rtl driver to support multiple interrupt domains and
remove hardcoded assumptions about the underlying demultiplex interrupt
- Remove the unused IMGPDC driver, which got orphaned when the metag
architecture was removed long ago.
- Update the Qualcom PDC interrupt chip driver to support differnent
versions of the IP block, to properly differentiable between direct and
GPIO based interrupts and to utilize pass through mode to the
underlying GIC interrupt.
- Remove redundant dev_err() and dev_err_probe() invocations in various
drivers as that error logging has been moved to devm_request_*_irq().
- Support dynamic MSI-X allocations in the GIC-V3-ITS MSI parent domain
driver. That's important for VFIO pass through devices to avoid
reinitialization of the MSI-X space when extending the vector
range. Such a reinitialization can result is lost interrupts and stale
devices.
- Fix a bunch of resource leaks in various driver error paths/
- The usual small improvements all over the place
