Subject: [PATCH AUTOSEL 4.19 091/252] PCI: iproc: Apply quirk_paxc_bridge() for module as well as built-in
Date: Fri, 14 Feb 2020 11:09:06 -0500 [thread overview]
Message-ID: <20200214161147.15842-91-sashal@kernel.org> (raw)
In-Reply-To: <20200214161147.15842-1-sashal@kernel.org>
From: Wei Liu <wei.liu@kernel.org>
[ Upstream commit 574f29036fce385e28617547955dd6911d375025 ]
Previously quirk_paxc_bridge() was applied when the iproc driver was
built-in, but not when it was compiled as a module.
This happened because it was under #ifdef CONFIG_PCIE_IPROC_PLATFORM:
PCIE_IPROC_PLATFORM=y causes CONFIG_PCIE_IPROC_PLATFORM to be defined, but
PCIE_IPROC_PLATFORM=m causes CONFIG_PCIE_IPROC_PLATFORM_MODULE to be
defined.
Move quirk_paxc_bridge() to pcie-iproc.c and drop the #ifdef so the quirk
is always applied, whether iproc is built-in or a module.
[bhelgaas: commit log, move to pcie-iproc.c, not pcie-iproc-platform.c]
