Subject: [PATCH v2 0/2] PCI: uniphier: Fix INTx masking/unmasking
Date: Mon, 30 Aug 2021 11:22:36 +0900 [thread overview]
Message-ID: <1630290158-31264-1-git-send-email-hayashi.kunihiko@socionext.com> (raw)
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
