Subject: [PATCH v2 0/4] NVIDIA Tegra Video Decoder driver improvements
Date: Tue, 18 Jun 2019 19:14:51 +0300	[thread overview]
Message-ID: <20190618161458.20499-1-digetx@gmail.com> (raw)

Hello,

This series cleans up some of minor shortcomings that are caused by
checkpatch recommendations that are not very applicable for the driver.
Then IOMMU support is added to the driver and now it can handle sparse
memory buffers that GPU hands to VDE in a default kernel configuration
on Tegra30+.

Changelog:

v2: - Fixed use-after-free bug and uninitialized-variable warning that
      were reported by smatch and pointed out by Hans Verkuil in the
      review comment to v1.

    - Fixed build failure when CONFIG_ARM_DMA_USE_IOMMU=y and tested this
      case properly (multi-platform kernel config).

    - Made some extra minor changes, prettifying code a tad more.
