In sur40_probe(), if video_register_device() fails, the error path jumps to
err_unreg_video. This incorrectly attempts to unregister a video device
that was never successfully registered, and fails to free the V4L2 control
handler (v4l2_ctrl_handler_free) that was initialized immediately prior.

Fix this by introducing an err_free_ctrl label to properly free the V4L2
control handler and bypass video_unregister_device() when video device
registration fails.

In sur40_probe(), input_register_device() was previously called early before
the V4L2 video device and vb2_queue components were fully initialized. If
userspace opened the input device immediately upon registration, sur40_open()
would trigger and start the sur40_poll() worker thread. This worker thread
invokes sur40_process_video() and accesses the uninitialized vb2_queue
structure, leading to a data race and potential system crash.

Furthermore, if V4L2 or video registration failed after input_register_device()
succeeded, the error path fell through to calling input_free_device() on a
successfully registered device instead of input_unregister_device(), corrupting
input core state.

Move input_register_device() to the very end of sur40_probe(). This ensures
the V4L2 and video queue structures are fully initialized before polling can
start, and naturally resolves the error path bug since input_free_device()
is now only called when input registration has not yet occurred.

To maintain strict LIFO (Last-In, First-Out) teardown ordering, also move
input_unregister_device() to the very beginning of sur40_disconnect(). This
guarantees that the input polling worker thread is stopped before V4L2
video components or control handlers are unregistered.

The driver allocates max_touch_num input slots, which are indexed from
zero through max_touch_num - 1. The current check allows a finger ID
equal to max_touch_num to reach cst3xx_report_contact(). While the input
core ignores out-of-range slot indices, reporting touch data without a
valid slot change corrupts the touch state of the previously active slot.

The touch count is read from the controller's report and is used to
index the fixed-size report buffer without first checking its range.
Reject counts larger than the supported number of touch slots before
checking the trailing byte or parsing touch data.

Reject finger IDs equal to or greater than max_touch_num, and return
immediately when an invalid finger ID is encountered so that corrupt
touch frames are discarded instead of reporting partial contact state.

The V821 Avaota F1 board configures the vendor driver with one touch
slot, so finger ID 1 is already invalid on that device.

The per-contact slot id is taken from the top nibble of the third
report byte, so it can be any value from 0 to 15. The driver only
allocates max_support_points MT slots (2 to 10 depending on the
variant), so a report that carries an id at or above that count - be it
a genuinely higher-numbered contact or a corrupted byte - is outside the
range the input core was told about.

input_mt_slot() silently ignores an ABS_MT_SLOT beyond num_slots and
leaves the current slot unchanged, so the following
input_mt_report_slot_state()/touchscreen_report_pos() pair is applied to
whichever slot happened to be selected last, reporting the contact at the
wrong position. Skip such entries instead.

If the touchscreen controller reports a touch ID of 0, the driver
calculates the slot ID as touch-&gt;id - 1, which underflows to UINT_MAX.
This is passed to input_mt_slot() as -1.

Since the input core ignores negative slot values, the active slot remains
unchanged. The driver then reports the touch coordinates for the previously
active slot, corrupting its state.

Fix this by rejecting touch reports with ID 0.

can be dropped completely, only a few drivers need one or two headers
added.

Replace the #include of &lt;linux/mod_devicetable.h&gt; by the more specific
&lt;linux/device-id/*.h&gt; where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

<title>Input: mms114 - fix touch indexing for MMS134S and MMS136</title>

The MMS134S and MMS136 touch controllers have an event size of 6 bytes
rather than 8 bytes. When __mms114_read_reg() reads the touch data
packet from the device into the touch buffer, the events are packed
tightly at 6-byte intervals. However, the driver iterates through the
events using standard C array indexing (touch[index]), where each
element is sizeof(struct mms114_touch) (8 bytes) apart. As a result, any
touch events beyond the first one are read from incorrect offsets and
parsed improperly.

Fix this by explicitly calculating the byte offset for each touch event
based on the device's specific event size.
