The pullup may be already enabled before the driver is initialized. This
happens for instance on JZ4740.
It has to be disabled at init time, as we cannot guarantee that a gadget

When disconnected as USB B-device, suspend interrupt should come before
diconnect interrupt, because the DP/DM pins are shorter than the
VBUS/GND pins on the USB connectors. But we sometimes get a suspend
interrupt after disconnect interrupt. In that case we have devctl set to
99 with VBUS still valid and musb_pm_runtime_check_session() wrongly
thinks we have an active session. We have no other interrupts after
disconnect coming in this case at least with the omap2430 glue.
Let's fix the issue by checking the interrupt status again with
delayed work for the devctl 99 case. In the suspend after disconnect
case the devctl session bit has cleared by then and musb can idle.
For a typical USB B-device connect case we just continue with normal
interrupts.

We currently punt any short read on a regular file to async context,
but this fails if the short read is due to running into EOF. This is
especially problematic since we only do the single prep for commands
now, as we don't reset kiocb->ki_pos. This can result in a 4k read on
a 1k file returning zero, as we detect the short read and then retry
from async context. At the time of retry, the position is now 1k, and
we end up reading nothing, and hence return 0.
Instead of trying to patch around the fact that short reads can be
legitimate and won't succeed in case of retry, remove the logic to punt
a short read to async context. Simply return it.

vm_ops is now initialized in ib_uverbs_mmap() with the recent rdma mmap
API changes. Earlier it was done in rdma_umap_priv_init() which would not
be called unless a driver called rdma_user_mmap_io() in its mmap.
i40iw does not use the rdma_user_mmap_io API but sets the vma's
vm_private_data to a driver object. This now conflicts with the vm_op
rdma_umap_close as priv pointer points to the i40iw driver object instead
of the private data setup by core when rdma_user_mmap_io is called. This
leads to a crash in rdma_umap_close with a mmap put being called when it
should not have.
Remove the redundant setting of the vma private_data in i40iw as it is not
used. Also move i40iw over to use the rdma_user_mmap_io API. This gives
the extra protection of having the mappings zapped when the context is
detsroyed.

When userspace requests a video mode parameter value that is not
supported, frame buffer device drivers should round it up to a supported
value, if possible, instead of just rejecting it. This allows
applications to quickly scan for supported video modes.
Currently this rule is not followed for the number of bits per pixel,
causing e.g. "fbset -depth N" to fail, if N is smaller than the current
number of bits per pixel.
Fix this by returning an error only if bits per pixel is too large, and
setting it to the current value otherwise.

In commit 0b8e7bbde5 ("drm/sun4i: tcon: Set min division of TCON0_DCLK
to 1.") it was assumed that all TCON variants support a minimum divider
of 1 if only DCLK was used.
However, the oldest generation of hardware only supports minimum divider
of 4 if only DCLK is used. If a divider of 1 was used on this old
hardware, some scrolling artifact would appear. A divider of 2 seemed
OK, but a divider of 3 had artifacts as well.
Set the minimum divider when outputing to parallel RGB based on the
hardware model, with a minimum of 4 for the oldest (A10/A10s/A13/A20)
hardware, and a minimum of 1 for the rest. A value is not set for the
TCON variants lacking channel 0.
This fixes the scrolling artifacts seen on my A13 tablet.

On some laptops enabling wakeup on the GPIO interrupts used for ACPI _AEI
event handling causes spurious wakeups.
This commit adds a new honor_wakeup option, defaulting to true (our current
behavior), which can be used to disable wakeup on troublesome hardware
to avoid these spurious wakeups.
This is a workaround for an architectural problem with s2idle under Linux
where we do not have any mechanism to immediately go back to sleep after
wakeup events, other then for embedded-controller events using the standard
ACPI EC interface, for details see:
https://lore.kernel.org/linux-acpi/61450f9b-cbc6-0c09-8b3a-aff6bf9a0b3c@redhat.com/

Revert changes done in commit f6ec948309 ("drm/i915: extend audio
CDCLK>=2*BCLK constraint to more platforms"). Audio drivers
communicate with i915 over HDA bus multiple times during system
boot-up and each of these transactions result in matching
get_power/put_power calls to i915, and depending on the platform,
a modeset change causing visible flicker.
GLK is the only platform with minimum CDCLK significantly lower
than BCLK, and thus for GLK setting a higher CDCLK is mandatory.
For other platforms, minimum CDCLK is close but below 2*BCLK
(e.g. on ICL, CDCLK=176.4kHz with BCLK=96kHz). Spec-wise the constraint
should be set, but in practise no communication errors have been
reported and the downside if set is the flicker observed at boot-time.
Revert to old behaviour until better mechanism to manage
probe-time clocks is available.
The full CDCLK>=2*BCLK constraint is still enforced at pipe
enable time in intel_crtc_compute_min_cdclk().

In meson_pinconf_get_drive_strength, variable bit is calculated by
meson_calc_reg_and_bit, this value is the offset from the first pin of a
certain bank to current pin, while Meson SoCs use two bits for each pin
to depict drive-strength. So a left shift by 1 should be done or node
pinconf-pins shows wrong message.

In a rare randconfig build I came across one configuration that does
not enable CONFIG_GPIOLIB, which is needed by lochnagar:

ERROR: "gpiochip_generic_free" [drivers/pinctrl/cirrus/pinctrl-lochnagar.ko] undefined!

Add another 'select' like all other pinctrl drivers have.

must not return an error if interrupts are not defined. Don't return an
error in case of -ENXIO.

- kbuild found missing define of MCOUNT_INSN_SIZE for various build configs
- Initialize variable to zero as gcc thinks it is used undefined
(it really isn't but the code is subtle enough that this doesn't hurt)
- Convert from do_div() to div64_ull() to prevent potential divide by zero
- Unregister a trace point on error path in sched_wakeup tracer
- Use signed offset for archs that can have stext not be first
- A simple indentation fix (whitespace error)
