2019-06-24media: Revert "[media] marvell-ccic: reset ccic phy when stop streaming for ↵Lubomir Rintel
stability" This accesses the clock registers directly and thus is going to stay in the way of making the driver devicetree friendly. No boards seems to actually use this. If it's somehow actually needed it needs to be done differently. This reverts commit 7c269f454e7a51b151d94f99344120efa1cd0acb.

In the patch refactoring the fw-node, the mt9m111 was broken for all platform_data based platforms, which were the first aim of this driver. Only the devicetree platform are still functional, probably because the testing was done on these. The result is that -EINVAL is systematically return for such platforms, what this patch fixes.

2019-06-21media: staging: media: tegra-vde: Manually pack UAPI structuresDmitry Osipenko
The __packed macro isn't available in userspace with the kernel headers. Checkpatch asks to use the macro, which is unwanted in a case of a UAPI header. There is no much benefit in a tight packing of the structures, hence let's pack them manually to cleanup things a tad. Note that there is no old-stable userspace that will suffer from this change, hence it's fine to change the ABI. In a result also more space is reserved for a possible future expansion of the UAPI as it was already shown that more fields will be needed for a later SoC generations.
