[PATCH v3 0/3] PCI: rzg3s: Fix issues in cleanup paths

From: Lad Prabhakar <[email protected]>

Hi all,

This series fixes a few issues in the cleanup paths of the Renesas RZ/G3S
PCIe host controller driver. The fixes include:
- Disabling the PCIe reference clock on probe failure.
- Propagating the original error code from platform_get_irq_byname() to
allow probe deferral.
- Unwinding chained handler registration on error in
rzg3s_pcie_init_irqdomain() and clearing chained handlers in
rzg3s_pcie_teardown_irqdomain() to avoid leaving stale handler and data
pointers attached to the parent interrupts.


v2->v3:
- Added rzg3s_pcie_teardown_intx() helper to remove the irqdomain
  and clear chained handlers.
- Updated commit message for patch 3.

Cheers,
Prabhakar
