There are a few implementations of string helpers in the tree like yesno()
that just returns "yes" or "no" depending on a boolean argument. Those
are helpful to output strings to the user or log.
In order to consolidate them, prefix all of them str_ prefix to make it
clear what they are about and avoid symbol clashes.
Taking the commoon `val ? "yes" : "no"` implementation, quite a few
users of open coded yesno() could later be converted to the new
function:
$ git grep '?\s*"yes"\s*' | wc -l
286
$ git grep '?\s*"no"\s*' | wc -l
20
The inlined function should keep the const strings local to each
compilation unit, the same way it's now, thus not changing the current
behavior.

The lvds.yaml file so far was both defining the generic LVDS properties
(such as data-mapping) that could be used for any LVDS sink, but also
the panel-lvds binding.
That last binding was to describe LVDS panels simple enough, and had a
number of other bindings using it as a base to specialise it further.
However, this situation makes it fairly hard to extend and reuse both
the generic parts, and the panel-lvds itself.
Let's remove the panel-lvds parts and leave only the generic LVDS
properties.

Recently we added generic "edp-panel"s probed by EDID. To support
panels in this way we look at the panel ID in the EDID and look up the
panel in a table that has power sequence timings. If we find a panel
that's not in the table we will still attempt to use it but we'll use
conservative timings. While it's likely that these conservative
timings will work for most nearly all panels, the performance of
turning the panel off and on suffers.
We'd like to be able to reliably detect the case that we're using the
hardcoded timings without relying on parsing dmesg. This allows us to
implement tests that ensure that no devices get shipped that are
relying on the conservative timings.
Let's add a new sysfs entry to panel devices. It will have one of:
* UNKNOWN - We tried to detect a panel but it wasn't in our table.
* HARDCODED - We're not using generic "edp-panel" probed by EDID.
* A panel name - This is the name of the panel from our table.

Hammer it a bit more in that iterators can be restarted and when that
matters, plus suggest to prefer the locked version whenver.
Also delete the two leftover kerneldoc for static functions plus
sprinkle some more links while at it.

The allow_fb_modifiers flag is unnecessary since it has been replaced
with fb_modifiers_not_supported flag.
v3:
- change the order as follows:
1. add fb_modifiers_not_supported flag
2. add default modifiers
3. remove allow_fb_modifiers flag

If only linear modifier is advertised, since there are many drivers that
only linear supported, the DRM core should handle this rather than
open-coding in every driver. However, there are legacy drivers such as
radeon that do not support modifiers but infer the actual layout of the
underlying buffer. Therefore, a new flag fb_modifiers_not_supported is
introduced for these legacy drivers, and allow_fb_modifiers is replaced
with this new flag.
v3:
- change the order as follows:
1. add fb_modifiers_not_supported flag
2. add default modifiers
3. remove allow_fb_modifiers flag
- add a conditional disable in amdgpu_dm_plane_init()

pm_runtime_get_sync() will increase the rumtime PM counter
even when it returns an error. Thus a pairing decrement is needed
to prevent refcount leak. Fix this by replacing this API with
pm_runtime_resume_and_get(), which will not change the runtime
PM counter on error. Besides, a matching decrement is needed
on the error handling path to keep the counter balanced.

binfmt_misc: fix crash when load/unload module
include/linux/sysctl.h: fix register_sysctl_mount_point() return type
commit 6f1b228529ae introduces a regression which can deadlock as
follows:
Task1: Task2:
jbd2_journal_commit_transaction ocfs2_test_bg_bit_allocatable
spin_lock(&jh->b_state_lock) jbd_lock_bh_journal_head
__jbd2_journal_remove_checkpoint spin_lock(&jh->b_state_lock)
jbd2_journal_put_journal_head
jbd_lock_bh_journal_head
Task1 and Task2 lock bh->b_state and jh->b_state_lock in different
order, which finally result in a deadlock.
So use jbd2_journal_[grab|put]_journal_head instead in
ocfs2_test_bg_bit_allocatable() to fix it.

Patch series "ocfs2: fix a deadlock case".
This fixes a deadlock case in ocfs2. We firstly export jbd2 symbols
jbd2_journal_[grab|put]_journal_head as preparation and later use them
in ocfs2 insread of jbd_[lock|unlock]_bh_journal_head to fix the
deadlock.
This patch (of 2):
This exports symbols jbd2_journal_[grab|put]_journal_head, which will be
used outside modules, e.g. ocfs2.
