There is a PM usage counter decrement after zynqmp_qspi_init_hw()
without any refcount increment, which leads to refcount leak.Add

Currently, only SDHI on R-Car Gen2+ reinitializes the irq register
during reset but it should be done on all instances. We can move it from
the SDHI driver to the TMIO core, because we now have the
'sd_irq_mask_all' variable which carries the proper value to use. That
also means we can remove the initialization from tmio_mmc_probe()
because it calls tmio_mmc_reset(), too. We only move that
tmio_mmc_reset() call there a little to ensure 'sd_irq_mask_all' is
properly set.

Not all commands need to be retried in case of a timeout/failure. This is
the case for the eMMC sanitize command, for example, which is issued
through the ioctl interface. More precisely, in case of timeout, retrying
could make the user wait for a very long time as each retry loop could last
for a couple of minutes.
Therefore, let's not use retries for the eMMC sanitize command.

Commit b2d3bef1aa78 ("media: coda: Add a V4L2 user for control error
macroblocks count") add the control for the decoder devices. But
during streamon() this ioctl gets called for all (encoder and decoder)
devices and on encoder devices this causes a null pointer exception.
Fix this by setting the control only if it is really accessible.

Some of the H265 status flags are wrong. Redefine them to corespond to
Allwinner CedarC open source userspace library. Only one of these flags
is actually used and new value also matches value used in libvdpau-sunxi
library, which is proven to be working.
Note that wrong (old) value in right circumstances (in combination with
another H265 decoding bug) causes driver lock up. With this fix decoding
is still broken (green output) but at least driver doesn't lock up.

When controls are used together with the Request API, then for
each request a v4l2_ctrl_handler struct is allocated. This contains
the controls that can be set in a request. If a control is *not* set in
the request, then the value used in the most recent previous request
must be used, or the current value if it is not found in any outstanding
requests.
The framework tried to find such a previous request and it would set
the 'req' pointer in struct v4l2_ctrl_ref to the v4l2_ctrl_ref of the
control in such a previous request. So far, so good. However, when that
previous request was applied to the hardware, returned to userspace, and
then userspace would re-init or free that request, any 'ref' pointer in
still-queued requests would suddenly point to freed memory.
This was not noticed before since the drivers that use this expected
that each request would always have the controls set, so there was
never any need to find a control in older requests. This requirement
was relaxed, and now this bug surfaced.
It was also made worse by changeset
2fae4d6aabc8 ("media: v4l2-ctrls: v4l2_ctrl_request_complete() should always set ref->req")
which increased the chance of this happening.
The use of the 'req' pointer in v4l2_ctrl_ref was very fragile, so
drop this entirely. Instead add a valid_p_req bool to indicate that
p_req contains a valid value for this control. And if it is false,
then just use the current value of the control.
Note that VIDIOC_G_EXT_CTRLS will always return -EACCES when attempting
to get a control from a request until the request is completed. And in
that case, all controls in the request will have the control value set
(i.e. valid_p_req is true). This means that the whole 'find the most
recent previous request containing a control' idea is pointless, and
the code can be simplified considerably.
The v4l2_g_ext_ctrls_common() function was refactored a bit to make
it more understandable. It also avoids updating volatile controls
in a completed request since that was already done when the request
was completed.

DT properties
These allow describing all the Aspeed VUART attributes currently
available via sysfs. aspeed,lpc-interrupts provides a replacement for
the deprecated aspeed,sirq-polarity-sense property.

This splits dedicated aspeed_vuart_set_{sirq,lpc_address}() functions
out of the sysfs store functions in preparation for adding DT
properties that will be poking the same registers. While we're at it,
these functions now provide some basic bounds-checking on their
arguments.

Removed useless led_blink_hdl() prototype and definition.
Removed struct LedBlink_param. Removed LedBlink entries in
rtw_cmd_callback[] and in wlancmds[]. Everything related to LedBlink is
not anymore needed. Index of slots changed in arrays comments to reflect
current positions.

The comedi code came into the kernel back in 2008, but traces its
lifetime to much much earlier. It's been polished and buffed and
there's really nothing preventing it from being part of the "real"
portion of the kernel.
So move it to drivers/comedi/ as it belongs there.
Many thanks to the hundreds of developers who did the work to make this
happen.

The sdio_drv_priv structure is a small wrapper around sdio_driver in
linux/mmc/sdio_func.h with an added drv_registered integer.
drv_registered is never used anywhere in the driver and only assigned to
during the sdio registering and unregistering process. We can safely
remove sdio_drv_priv and use the sdio_driver structure directly.
