Subject: [cip-dev] [RFC PATCH 4.19.y-cip 24/50] PCI: endpoint: Replace spinlock with mutex
Date: Mon, 12 Oct 2020 15:19:07 +0100	[thread overview]
Message-ID: <20201012141933.9652-25-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)
In-Reply-To: <20201012141933.9652-1-prabhakar.mahadev-lad.rj@bp.renesas.com>

[-- Attachment #1: Type: text/plain, Size: 10278 bytes --]

From: Kishon Vijay Abraham I <kishon@ti.com>

commit 3d3248dbd018502f654064c78efcd2e165ab3486 upstream.

The pci_epc_ops is not intended to be invoked from interrupt context.
Hence replace spin_lock_irqsave and spin_unlock_irqrestore with
mutex_lock and mutex_unlock respectively.
