As pointed by Lars, this doesn't require a zero-check. Also, while looking
at this a little closer at it (again), the masking can be done later, as
there is a zero-check for 'mode_flags' anyway, which returns -EINVAL. And
we only need the 'mode_flags' later in the logic.
This change is more of a tweak.

When vfio_pin_pages_remote() returns with a partial batch consisting of
a single VM_PFNMAP pfn, a subsequent call will unfortunately try
restoring it from batch->pages, resulting in vfio mapping the wrong page
and unbalancing the page refcount.
Prevent the function from returning with this kind of partial batch to
avoid the issue. There's no explicit check for a VM_PFNMAP pfn because
it's awkward to do so, so infer it from characteristics of the batch
instead. This may result in occasional false positives but keeps the
code simpler.

The device's hardware reset pin is only required if the platform
must be able to update the device's firmware.
As such, demote the reset GPIO to optional in support of devices
that ship with pre-programmed firmware and don't route the reset
pin back to the SoC.
In that case, the 'fw_file' attribute is hidden because there is
no way to open the bootloader. The logic is extended to the case
in which the device does not advertise bootloader support in the
first place.
Last but not least, remove the hardware reset performed at probe
because there is no reason to reset the device manually. A power
on reset function already ensures a clean reset at start-up.

Now that the helper functions have been moved to drivers/input/ so
that all input devices may use them, the introductory comments can
be updated to remove any implication that the helper functions are
solely limited to touchscreens.
This patch also scrubs any remaining use of 'DT' since there isn't
any actual dependency on OF. A minor spelling error is resolved as
well ('setups' -> 'sets up').

Some devices outside of drivers/input/touchscreen/ can still make
use of the touchscreen helper functions. Therefore, it was agreed
in [1] to move them outside of drivers/input/touchscreen/ so that
other devices can call them without INPUT_TOUCHSCREEN being set.
As part of this change, 'of' is dropped from the filename because
the helpers no longer actually use OF. No changes are made to the
file contents whatsoever.
Based on the feedback in [2], the corresponding binding documents
(touchscreen.yaml and touchscreen.txt) are left in their original
locations.

The bootloader can be closed using the 'execute' command (0x02) or
hardware reset. Rather than using the former option for successful
firmware update procedures and reserving the latter for recovering
the device upon failure, simply use hardware reset for all cases.
The post-bootloader initialization delay increases marginally when
triggered by a hardware reset, so increase the wait time to ensure
the device does not subsequently fail to respond.
As part of this change, refactor the return path to avoid an extra
assignment and to make the logic a bit smaller.

The vendor-assigned firmware project number is restricted to the
generic project number (15); however the vendor may assign other
project numbers to specific applications and customers.
These custom project numbers may be based on forwards-compatible
firmware revision 1.x. However, the driver unnecessarily rejects
anything older than firmware revision 2.0.
To support other applications, remove these unnecessarily strict
checks and enter the bootloader only for truly incompatible A000
devices.

We want to be able to report the input event as soon as the debounce
delay elapsed. However, the current code does not really ensure that,
as it uses the jiffies-based schedule_delayed_work() API. With a small
enough HZ value (HZ <= 100), this results in some input events being
lost, when a key is quickly pressed then released (on a human's time
scale).
Switching to hrtimers fixes this issue, and will work even on extremely
low HZ values (tested at HZ=24). This is however only possible if
reading the GPIO is possible without sleeping. If this condition is not
met, the previous approach of using a jiffies-based timer is taken.

Dealing with input, timing is important; if the button should be
released in one millisecond, then it should be done in one millisecond
and not a hundred milliseconds.
Therefore, the standard timer API is not really suitable for this task.
Convert the gpio-keys driver to use a hrtimer instead of the standard
timer to address this issue.
Note that by using a hard IRQ for the hrtimer callback, we can get rid
of the spin_lock_irqsave() and spin_unlock_irqrestore().

In order to allow new firmware to load, it first needs to check if the
firmware version on file matches the one loaded if it doesn't, then it
needs to revert to bootloader mode in order to load the new firmware.

This checks the firmware build number, week and year against the
repective loaded version. If details are a match, skip the download
process.

Updated restricted chips have trouble processing multiple sequenced
operations. So remove the capability to sequence multiple operations and
reduce the maximum transfer size to 8 bytes.

Function hvfb_probe() calls hvfb_getmem(), expecting upon return that
info->apertures is either NULL or points to memory that should be freed
by framebuffer_release(). But hvfb_getmem() is freeing the memory and
leaving the pointer non-NULL, resulting in a double free if an error
occurs or later if hvfb_remove() is called.
Fix this by removing all kfree(info->apertures) calls in hvfb_getmem().
This will allow framebuffer_release() to free the memory, which follows
the pattern of other fbdev drivers.

Not setting the ipv6 bit while destroying ipv6 listening servers may
result in potential fatal adapter errors due to lookup engine memory hash
errors. Therefore always set ipv6 field while destroying ipv6 listening
servers.
