Subject: [PATCH v2 0/2] PCI: uniphier: Fix INTx masking/unmasking

This series includes some fixes to INTx masking/unmasking for UniPhier PCIe
host controller driver.

- Remove unnecessary bit clears to INTX mask field
- Remove unnecessary irq_ack() function because write access to status field
  doesn't work
- Add lock into callback functions to avoid race condition

Kunihiko Hayashi (2):
  PCI: uniphier: Fix INTx mask/unmask bit operation and remove ack
    function
  PCI: uniphier: Serialize INTx masking/unmasking
