Do not solely rely on compiler optimizations to get the workaround
of having macros do nothing using an empty do-while loop. It's
inefficient.
Use ((void)0) to which the standard assert macro expands when NDEBUG
is defined.
No functional change intended.

[ Upstream commit 206f533a0a7c683982af473079c4111f4a0f9f5e ]
From: Dmitry Torokhov <dmitry.torokhov@gmail.com>
When exercising uinput interface syzkaller may try setting up device
with a really large number of slots, which causes memory allocation
failure in input_mt_init_slots(). While this allocation failure is
handled properly and request is rejected, it results in syzkaller
reports. Additionally, such request may put undue burden on the
system which will try to free a lot of memory for a bogus request.
Fix it by limiting allowed number of slots to 100. This can easily
be extended if we see devices that can track more than 100 contacts.

num_slots is supplied from userspace using ioctl(UI_DEV_CREATE).

The Lenovo N24 on resume becomes stuck in a state where it
sends incorrect packets, causing elantech_packet_check_v4 to fail.
The only way for the device to resume sending the correct packets is for
it to be disabled and then re-enabled.
This change adds a dmi check to trigger this behavior on resume.

[ Upstream commit 38a38f5a36da9820680d413972cb733349400532 ]
When support for Silead touchscreens was orginal added some touchscreens
with older firmware versions only supported 5 fingers and this was made
the default requiring the setting of a "silead,max-fingers=10" uint32
device-property for all touchscreen models which do support 10 fingers.
There are very few models with the old 5 finger fw, so in practice the
setting of the "silead,max-fingers=10" is boilerplate which needs to
be copy and pasted to every touchscreen config.
Reporting that 10 fingers are supported on devices which only support
5 fingers doesn't cause any problems for userspace in practice, since
at max 4 finger gestures are supported anyways. Drop the max_fingers
configuration and simply always assume 10 fingers.

On some x86 tablets with a silead touchscreen the windows logo on the
front is a capacitive home button. Touching this button results in a touch
with bits 12-15 of the Y coordinates set, while normally only the lower 12
are used.
Detect this and report a KEY_LEFTMETA press when this happens. Note for
now we only respond to the Y coordinate bits 12-15 containing 0x01, on some
tablets *without* a capacative button I've noticed these bits containing
0x04 when crossing the edges of the screen.

[ Upstream commit a08b8f8557ad88ffdff8905e5da972afe52e3307 ]
This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1][2].
As the "ff" variable is a pointer to "struct ff_device" and this
structure ends in a flexible array:
struct ff_device {
[...]
struct file *effect_owners[] __counted_by(max_effects);
};
the preferred way in the kernel is to use the struct_size() helper to
do the arithmetic instead of the calculation "size + count * size" in
the kzalloc() function.
The struct_size() helper returns SIZE_MAX on overflow. So, refactor
the comparison to take advantage of this.
This way, the code is more readable and safer.
This code was detected with the help of Coccinelle, and audited and
modified manually.

commit 0774d19038c496f0c3602fb505c43e1b2d8eed85 upstream.
If an input device declares too many capability bits then modalias
string for such device may become too long and not fit into uevent
buffer, resulting in failure of sending said uevent. This, in turn,
may prevent userspace from recognizing existence of such devices.
This is typically not a concern for real hardware devices as they have
limited number of keys, but happen with synthetic devices such as
ones created by xen-kbdfront driver, which creates devices as being
capable of delivering all possible keys, since it doesn't know what
keys the backend may produce.
To deal with such devices input core will attempt to trim key data,
in the hope that the rest of modalias string will fit in the given
buffer. When trimming key data it will indicate that it is not
complete by placing "+," sign, resulting in conversions like this:
old: k71,72,73,74,78,7A,7B,7C,7D,8E,9E,A4,AD,E0,E1,E4,F8,174,
new: k71,72,73,74,78,7A,7B,7C,+,
This should allow existing udev rules continue to work with existing
devices, and will also allow writing more complex rules that would
recognize trimmed modalias and check input device characteristics by
other means (for example by parsing KEY= data in uevent or parsing
input device sysfs attributes).
Note that the driver core may try adding more uevent environment
variables once input core is done adding its own, so when forming
modalias we can not use the entire available buffer, so we reduce
it by somewhat an arbitrary amount (96 bytes).

[ Upstream commit 48c0687a322d54ac7e7a685c0b6db78d78f593af ]
The output voltage is inclusive hence the max level calculation is
off-by-one-step. Correct it.
iWhile we are at it also add a define for the step size instead of
using the magic value.

While input core can work with input->phys set to NULL userspace might
depend on it, so better fail probing if allocation fails. The system must
be in a pretty bad shape for it to happen anyway.

Give fingerprintd the highest priority (MIN_NICE) when the screen is off to
speed up fingerprint processing, and then reset its priority back to normal
when the screen is on.
There are now 2 fingerprint related processes:
- android.hardware.biometrics.fingerprint@2.1-service -> comm:fingerprint@2.1
- com.qualcomm.qti.biometrics.fingerprint.service -> comm:erprint.service
For the match to work properly, use strstr() with "erprint".
[ghostrider-reborn]
- device_available was being set to 0 during fp-unlock-and-wake
which led to niceness being stuck at -20 (except in dt2w)
- Also use xiaomi bridge interface hack to slightly reduce
unlock times, no idea why it was commented in the first place

[ Upstream commit 963465a33141d0d52338e77f80fe543d2c9dc053 ]
On a PC Engines APU our admins are faced with:
$ dmesg | grep -c "gpio-keys-polled gpio-keys-polled: unable to claim gpio 0, err=-517"
261
Such a message always appears when e.g. a new USB device is plugged in.
Suppress this message which considerably clutters the kernel log for
EPROBE_DEFER (i.e. -517).
