[PATCH 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.

Note:
- This patch applies on top of pci-next (commit - 5d9f1dd3b3e7).
- There is a patch [0] inflight for this driver which doesn't apply
  on pci-next. As there is a conflict between the two, the patch [0]
  will be rebased on top of this series and v3 will be sent out for review.

Cheers,
