Using %4s to format f->fmt.pix_mp.pixelformat in fdp1_try_fmt() and
fdp1_s_fmt() may lead to more characters being printed (when the byte
following field pixelformat is not zero).
Add ".4" to the format specifier to limit the number of printed
characters to four. The resulting format specifier "%4.4s" is also used
by other media drivers to print pixelformat value.

The LG Melfas touchscreen has a bad firmware where it declares the Contact ID
field as constant while it shouldn't. This messes up the autodetection and the
reporting of the events by hid-multitouch given that hid-input ignores constant
fields.
The autodetection is simply worked around by manually adding the device to
hid_have_special_driver[].
The processing of the events requires either a report fixup, or some specific
case handling. Given that the report fixup would require to basically rewrite
all the report descriptor, I went for the programatic way of fixing that after
the report descriptors are loaded.

Non-generic devices have numbered_buttons set for both pen and
touch interfaces by default. The actual number of buttons on the
interface is normally manually decided later, which is different
from what those HID generic devices are processed, where number
of buttons are directly retrieved from HID descriptors.
This patch adds the missed HID_GENERIC check and moves the statement
to wacom_setup_pad_input_capabilities since it's not a quirk anymore.

The STK1160 needs some time to transfer data to and from the AC97 codec.
The transfer completion is indicated by command read/write bits in the
chip's audio control register. The driver should poll these bits and
wait until they have been cleared by hardware before trying to retrieve
the results of a read operation or setting a new write command.

Some STK1160-based devices use the chip's internal 8-bit ADC. This is
configured through a strap pin. The value of this and other pins can be
read through the POSVA register. If the internal ADC is used, or if
audio is disabled altogether, there's no point trying to setup the AC97
codec.

Exposing all the channels of the device's internal AC97 codec to
userspace is unnecessary and confusing. Instead the driver should setup
the codec with proper values. This patch removes the mixer and sets up
the codec using optimal values, i.e. the same values set by the Windows
driver. This also makes the device work out-of-the-box, without the need
for the user to reconfigure the device every time it's plugged in.

Check that the control whose events we want to delete is still there.
Normally this will always be the case, but I am not 100% certain if
there aren't any corner cases when a device is forcibly unbound.
In any case, this will satisfy static checkers and simply make it more
robust.

Originally Toshiba told us that the only way to disable HDCP was to
set the receiver in repeater mode, that would make the authentication
fail because of missing software support. It has worked fine with all
the sources we and our customers has used, until it was reported
problems with Apple MacBook (Retina, 12-inch, Early 2015)
(https://support.apple.com/kb/SP712?locale=en_US&viewlocale=en_US)
with Apple A1612 USB type-C multiport adapter
(http://www.apple.com/shop/product/MJ1K2AM/A/usb-c-digital-av-multiport-adapter)
Finally Toshiba came up with a hidden bit that is named "Manual HDCP
authentication". In this patch the original "repeater mode" concept is
removed, and the new bit is set instead.
With his patch HDCP is disabled when connected to the Apple MacBook
and all other sources we have tested so far. The Apple MacBook is
constantly trying to authenticate, but fails and continues to transmit
unencrypted video.

The number of CSI lanes that should be used is set to the CSI_CONTROL
register by indirectly writing to the CSI_CONFW register. When the
number of lanes is read back from the CSI_CONTROL register the value
is usually correct, but we have seen that it suddenly is 1 for a short
moment before the correct value is restored again.
Toshiba have not figured out why that happen, but we have found it
safer to store the value in the driver.

dib7000p_read_word() may return zero on i2c errors, resulting in
dib7000p_get_internal_freq() returning zero.
So don't divide by the result of dib7000p_get_internal_freq()
without checking it for zero in dib7000p_set_dds().
On one of my machines the device
ID 2304:0229 Pinnacle Systems, Inc. PCTV Dual DVB-T 2001e
about once a day/every two days gets into a state, where
most (all?) I2C reads return with an error. Tuning during this
state will result in a divide by zero without this patch.
This patch doesn't fix the root cause for the device getting
into a bad state, but it allows me to unload/reload the drivers,
bringing it back into a usable state.

In tiqdio_call_inq_handlers(), we're looping over all

For devices with multiple input queues, tiqdio_call_inq_handlers()
iterates over all input queues and clears the device's DSCI
during each iteration. If the DSCI is re-armed during one
of the later iterations, we therefore do not scan the previous
queues again.
The re-arming also raises a new adapter interrupt. But its
handler does not trigger a rescan for the device, as the DSCI
has already been erroneously cleared.
This can result in queue stalls on devices with multiple
input queues.
Fix it by clearing the DSCI just once, prior to scanning the queues.
As the code is moved in front of the loop, we also need to access
the DSCI directly (ie irq->dsci) instead of going via each queue's
parent pointer to the same irq. This is not a functional change,
and a follow-up patch will clean up the other users.
In practice, this bug only affects CQ-enabled HiperSockets devices,
ie. devices with sysfs-attribute "hsuid" set. Setting a hsuid is
needed for AF_IUCV socket applications that use HiperSockets
communication.

In asds configured with V4L2_ASYNC_MATCH_OF, the v4l2 subdev can be
part of a devicetree overlay, for example:
&media_bridge {
...
my_port: port@0 {
#address-cells = <1>;
#size-cells = <0>;
reg = <0>;
ep: endpoint@0 {
remote-endpoint = <&camera0>;
};
};
};
/ {
fragment@0 {
target = <&i2c0>;
__overlay__ {
my_cam {
compatible = "foo,bar";
port {
camera0: endpoint {
remote-endpoint = <&my_port>;
...
};
};
};
};
};
};
Each time the overlay is applied, its of_node pointer will be
different. We are not interested in matching the pointer, what we
want to match is that the path is the one we are expecting. Change to
use of_node_cmp() so that we continue matching after the overlay has
been removed and reapplied.

The value of return variable ret is 0 on some error paths, for example,
when pci_resource_start() returns a NULL pointer. 0 means no error in
this context, which is contrary to the fact. This patch fixes the bug.

Function bdisp_debugfs_create() returns 0 even on errors. So its caller
cannot detect the errors. It may be better to return "-ENOMEM" on the
exception paths.

Eliminate a double-add by creating a new list to manage
command descriptors when created; move the descriptor to
the pending list when the command is submitted.

An I/O page fault occurs when the IOMMU is enabled on a
system that supports the v5 CCP. DMA operations use a
Request ID value that does not match what is expected by
the IOMMU, resulting in the I/O page fault. Setting the
Request ID value to 0 corrects this issue.

gcc isn't smart enough to realize it can share most of the argument
buildup and the actual function call between the two branches, so help
it a little.

It takes more .text to initialize these on the stack than they occupy
in .rodata, so just make them static const.

ibuf and rbuf in lme2510_int_response are always assigned to before they
are read, and their addresses do not escape the function, so they have
no reason to be static.
