Commit d595567dc4f0 (MD: fix invalid stored role for a disk) broke linear

vga_switcheroo: Fix missing gpu_bound call at audio client registration

2018-11-13T19:09:00+00:00

commit fc09ab7a767394f9ecdad84ea6e85d68b83c8e21 upstream.

The commit 37a3a98ef601 ("ALSA: hda - Enable runtime PM only for
discrete GPU") added a new ops gpu_bound to be called when GPU gets
bound.  The patch overlooked, however, that vga_switcheroo_enable() is
called only once at GPU is bound.  When an audio client is registered
after that point, it would miss the gpu_bound call.  This leads to the
unexpected lack of runtime PM in HD-audio side.

For addressing that regression, just call gpu_bound callback manually
at vga_switcheroo_register_audio_client() when the GPU was already
bound.

vt: fix broken display when running aptitude

2018-11-13T19:09:00+00:00

commit 943210ba807ec50aafa2fa7b13bd6d36a478969b upstream.

If you run aptitude on framebuffer console, the display is corrupted. The
corruption is caused by the commit d8ae7242. The patch adds "offset" to
"start" when calling scr_memsetw, but it forgets to do the same addition
on a subsequent call to do_update_region.

soc/tegra: pmc: Fix child-node lookup

2018-11-13T19:08:55+00:00

commit 1dc6bd5e39a29453bdcc17348dd2a89f1aa4004e upstream.

Fix child-node lookup during probe, which ended up searching the whole
device tree depth-first starting at the parent rather than just matching
on its children.

To make things worse, the parent pmc node could end up being prematurely
freed as of_find_node_by_name() drops a reference to its first argument.

commit 137dc5843faeacabf48fc22a8dc58c4e0b4f0927 upstream.

The scm device must be present in order for the rmtfs driver to
configure memory permissions for the rmtfs memory region, so check that
it is probed before continuing.

rpmsg: smd: fix memory leak on channel create

commit 940c620d6af8fca7d115de40f19870fba415efac upstream.

Currently a failed allocation of channel->name leads to an
immediate return without freeing channel. Fix this by setting
ret to -ENOMEM and jumping to an exit path that kfree's channel.

commit 463659a08d7999d5461fa45b35b17686189a70ca upstream.

These names have been renamed in the CTA-861 standard due to trademark
issues. Replace them here as well so they are in sync with the standard.

commit db0340182444612bcadb98bdec22f651aa42266c upstream.

The CTA-861 standards have been updated to refer to opRGB instead
of AdobeRGB. The official standard is in fact named opRGB, so
switch to that.

The two old defines referring to ADOBERGB in the public API are
put under #ifndef __KERNEL__ and a comment mentions that they are
deprecated.

drm/mediatek: fix OF sibling-node lookup

2018-11-13T19:08:54+00:00

commit ceff2f4dcd44abf35864d9a99f85ac619e89a01d upstream.

Use the new of_get_compatible_child() helper to lookup the sibling
instead of using of_find_compatible_node(), which searches the entire
tree from a given start node and thus can return an unrelated (i.e.
non-sibling) node.

This also addresses a potential use-after-free (e.g. after probe
deferral) as the tree-wide helper drops a reference to its first
argument (i.e. the parent device node).

While at it, also fix the related cec-node reference leak.

commit ab83203e181015b099720aff43ffabc1812e0fb3 upstream.

When there is no EDID the CEC adapter should be unconfigured as
well. So call cec_phys_addr_invalidate() when this happens.
