Subject: [PATCH v2 0/9] iommu: Permit modular builds of ARM SMMU[v3] drivers
Date: Fri,  8 Nov 2019 15:15:59 +0000
Message-ID: <20191108151608.20932-1-will@kernel.org> (raw)

Hi all,

This is version two of the patches I previously posted here:

  https://lore.kernel.org/lkml/20191030145112.19738-1-will@kernel.org/

Changes since v1 include:

  * Build single "arm-smmu-mod.ko" module for the Arm SMMU driver
  * Hold a reference to the IOMMU driver module across {add,remove}_device()
  * Take a reference to the IOMMU driver module during of_xlate()
  * Added Bjorn's ack on the PCI export patch

Please note that I haven't been able to test this properly, since I don't
currently have access to any Arm SMMU hardware.

Cheers,

Will
