The deprecated UNIVERSAL_DEV_PM_OPS() macro uses the provided callbacks
for both runtime PM and system sleep, which is very likely to be a
mistake, as a system sleep can be triggered while a given device is
already PM-suspended, which would cause the suspend callback to be
called twice.
The amount of users of UNIVERSAL_DEV_PM_OPS() is also tiny (16
occurences) compared to the number of places where
SET_SYSTEM_SLEEP_PM_OPS() is used with pm_runtime_force_suspend() and
pm_runtime_force_resume(), which makes me think that none of these cases
are actually valid.
As the new macro DEFINE_UNIVERSAL_DEV_PM_OPS() which was introduced to
replace UNIVERSAL_DEV_PM_OPS() is currently unused, remove it before
someone starts to use it in yet another invalid case.

Pull pin control bulk updates from Linus Walleij:
"Core changes:
- New standard enumerator and corresponding device tree bindings for
output impedance pin configuration. (Implemented and used in the
Renesas rzg2l driver.)
- Cleanup of Kconfig and Makefile to be somewhat orderly and
alphabetic.
New drivers:
- Samsung Exynos 7885 pin controller.
- Ocelot LAN966x pin controller.
- Qualcomm SDX65 pin controller.
- Qualcomm SM8450 pin controller.
- Qualcomm PM8019, PM8226 and PM2250 pin controllers.
- NXP/Freescale i.MXRT1050 pin controller.
- Intel Thunder Bay pin controller.
Enhancements:
- Introduction of the string library helper function
"kasprintf_strarray()" and subsequent use in Rockchip, ST and
Armada pin control drivers, as well as the GPIO mockup driver.
- The Ocelot pin controller has been extensively rewritten to use
regmap and other modern kernel infrastructure.
- The Microchip SGPIO driver has been converted to use regmap.
- The SPEAr driver had been converted to use regmap.
- Substantial cleanups and janitorial on the Apple pin control driver
that was merged for v5.16.
- Janitorial to remove of_node assignments in the GPIO portions that
anyway get this handled in the GPIO core.
- Minor cleanups and improvements in several pin controllers"

Commit a5d3d1adc9 ("leds: lp55xx: Initialize enable GPIO direction to
output") attempts to fix this, but the fix did not work since at least
for the Nokia N900 the value needs to be set to HIGH, per the device
tree. So rather than hardcoding the value to a potentially invalid value
for some devices, let's set direction in lp55xx_init_device.

While I was auditing the code in xfs_repair that adds feature bits to
existing V5 filesystems, I decided to have a look at how online fsck
handles feature bits, and I found a few problems:
1) ATTR2 is added to the primary super when an xattr is set to a file,
but that isn't consistently propagated to secondary supers. This isn't
a corruption, merely a discrepancy that repair will fix if it ever has
to restore the primary from a secondary. Hence, if we find a mismatch
on a secondary, this is a preen condition, not a corruption.
2) There are more compat and ro_compat features now than there used to
be, but we mask off the newer features from testing. This means we
ignore inconsistencies in the INOBTCOUNT and BIGTIME features, which is
wrong. Get rid of the masking and compare directly.
3) NEEDSREPAIR, when set on a secondary, is ignored by everyone. Hence
a mismatch here should also be flagged for preening, and online repair
should clear the flag. Right now we ignore it due to (2).
4) log_incompat features are ephemeral, since we can clear the feature
bit as soon as the log no longer contains live records for a particular
log feature. As such, the only copy we care about is the one in the
primary super. If we find any bits set in the secondary super, we
should flag that for preening, and clear the bits if the user elects to
repair it.
