DAPM models various widgets but lacks a sink widget.
DSPs can have modules which take audio data, process it and are
capable of generating events thus acting as a sink of data.
To make the dapm graph complete for such paths we need a dapm
sink widget for these modules, so add a SND_SOC_DAPM_SINK to
declare such a widget. This widget will be treated as
SND_SOC_DAPM_EP_SINK endpoint in the dapm graph

header is updated automatically if requested, however no updates for any

Various files are owned by root with 0440 permission. Reading them is
impossible in an unprivileged user namespace, interfering with firewall
tools. For instance, iptables-save relies on /proc/net/ip_tables_names
contents to dump only loaded tables.
This patch assigned ownership of the following files to root in the
current namespace:
- /proc/net/*_tables_names
- /proc/net/*_tables_matches
- /proc/net/*_tables_targets
- /proc/net/nf_conntrack
- /proc/net/nf_conntrack_expect
- /proc/net/netfilter/nfnetlink_log
A mapping for root must be available, so this order should be followed:

Since commit 3fffd12839 ("i2c: allow specifying

automatic wakeup irq support for i2c devices. That
commit missed the fact that rtc-1307 had its own
wakeup irq handling and ended up introducing a
kernel splat for at least Beagle x15 boards.
Fix that by reverting original commit _and_ passing
correct interrupt names on DTS so i2c-core can
choose correct IRQ as wakeup.
Now that we have automatic wakeirq support, we can
revert the original commit which did it manually.

now may get a warning from:

in drm_vblank_count_and_time(). Prior to this change, we would end
up making out-of-bounds array accesses via:
struct drm_vblank_crtc *vblank = &dev->vblank[crtc];
and
*vblanktime = vblanktimestamp(dev, pipe, cur_vblank);

else

foo() will be called for each domain *not* in mask, if condition holds,

Fix this by reversing the conditions in the macros, and adding an else

There's a few places where we need to access a GPC register from ucode,
but outside of the falcon's io address space. To do this we need to
calculate the offset based on which GPC we're executing on.
This used to be done manually, but we've since found a "base" offset
that can be added by the hardware. To use this, an extra bit needs to
be set in the register address, which is what this macro achieves.
