Remove use of regmap_irq_get_virq() in driver probe which was
conflicting with use of platform_get_irq_byname().
platform_get_irq_byname() already returns the VIRQ number due
to MFD core translation so using regmap_irq_get_virq() on that
returned value results in an incorrect IRQ being requested.
The driver probes then fail because of this.

Commit c420619 "pinctrl: pinconf: remove checks on ops->pin_config_get"
removed the check on (ops != NULL) when performing pinconf_pins_show() or
pinconf_groups_show(). As these entries are always enabled, even if
pinconf is not supported, reading will result in an oops due to NULL
ops.
Instead of checking for ops, remove the corresponding debugfs entries if
pinconf and/or pinmux are not implemented.
Tested on OMAP3 (pinctrl-single).

A couple of vmwgfx fixes together with missing bits of legacy device
emulation to facilitate old user-space drivers on new devices.
The shader emulation bits are a bit large, but since they mostly touch the
new device code, regressions are unlikely. I figure the gain of having
this from the start clearly outweighs the risc of adding these bits at
this point.

This is becase device->handler is NULL in acpi_device_hotplug().
This case was used to fail in acpi_hotplug_notify_cb() as the target
had no acpi_deivce. However, acpi_device now exists after ejection.
Added a check to verify if acpi_device->handler is valid for an
eject request in acpi_hotplug_notify_cb(). Note that handler passed
from an argument is still valid while acpi_device->handler is NULL.

When a context is first referenced in the command stream, make sure that all
scrubbed (as a result of eviction) bindings are re-emitted. Also make sure that
all bound resources are put on the resource validate list.
This is needed for legacy emulation, since legacy user-space drivers will
typically not re-emit shader bindings. It also removes the requirement for
user-space drivers to re-emit render-target- and texture bindings.

behave like reservation calls"
The call to ttm_eu_backoff_reservation() as part of an error path would cause
a lock imbalance if the reservation ticket was not initialized. This error is
easily triggered from user-space by submitting a bogus command stream.

On HP EliteBook Revolve 810 the ACPI backlight device doesn't work as
expected. For example when resuming from system sleep, it seems to lose
backlight settings.
Forcing Intel driver fixes the problem so add this machine the ACPI

We have few fedora bug reports about list corruption on pinctrl,
for example:
https://bugzilla.redhat.com/show_bug.cgi?id=1051918
Most likely corruption happen due lack of protection of pinctrl_list
when adding new nodes to it. Patch corrects that.
Fixes: 42fed7ba44e ("pinctrl: move subsystem mutex to pinctrl_dev struct")

A source sending a GTF (Generalized Timing Formula) format have no means of
