Pull input fixes from Dmitry Torokhov:
- a fix for cm109 stomping on its own control URB if it tries to toggle
buzzer immediately after userspace opens input device (found by
syzcaller)- another fix for Raydium touchscreens that do not like splitting
command transfers- quirks for i8042, soc_button_array, and goodix drivers to make them
work better with certain hardware.* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: goodix - add upside-down quirk for Teclast X98 Pro tablet
Input: cm109 - do not stomp on control URB
Input: i8042 - add Acer laptops to the i8042 reset list
Input: cros_ec_keyb - send 'scancodes' in addition to key events
Input: soc_button_array - add Lenovo Yoga Tablet2 1051L to the dmi_use_low_level_irq list

We need to make sure we are not stomping on the control URB that was
issued when opening the device when attempting to toggle buzzer.
To do that we need to mark it as pending in cm109_open().Reported-and-tested-by: syzbot+150f793ac5bc18eee150@syzkaller.appspotmail.com

To let userspace know what 'scancodes' should be used in EVIOCGKEYCODE
and EVIOCSKEYCODE ioctls, we should send EV_MSC/MSC_SCAN events in
addition to EV_KEY/KEY_* events. The driver already declared MSC_SCAN
capability, so it is only matter of actually sending the events.Link: https://lore.kernel.org/r/X87aOaSptPTvZ3nZ@google.com

Raydium device does not like splitting of tx transactions into multiple
messages - one for the register address and one for the actual data. This
results in incorrect behavior on the device side.This change updates raydium_i2c_read and raydium_i2c_write to create
i2c_msg arrays separately and passes those arrays into raydium_i2c_xfer
which decides based on the address whether the bank switch command should
be sent. The bank switch header is still added by raydium_i2c_read and
raydium_i2c_write to ensure that all these operations are performed as part
of a single I2C transfer. It guarantees that no other transactions are
initiated to any other device on the same bus after the bank switch command
is sent.Signed-off-by: Furquan Shaikh

After commit 74d905d2d38a devices requiring the workaround for edge
triggered interrupts stopped working.The hardware needs the quirk to be used before even proceeding to
check if the quirk is needed because mxt_acquire_irq() is called
before mxt_check_retrigen() is called and at this point pending IRQs
need to be checked, and if the workaround is not active, all
interrupts will be lost from this point.Solve this by switching the calls around.

The i8042 module exports several symbols which may be used by other
modules.Before this commit it would refuse to load (when built as a module itself)
on systems without an i8042 controller.This is a problem specifically for the asus-nb-wmi module. Many Asus
laptops support the Asus WMI interface. Some of them have an i8042
controller and need to use i8042_install_filter() to filter some kbd
events. Other models do not have an i8042 controller (e.g. they use an
USB attached kbd).Before this commit the asus-nb-wmi driver could not be loaded on Asus
models without an i8042 controller, when the i8042 code was built as
a module (as Arch Linux does) because the module_init function of the
i8042 module would fail with -ENODEV and thus the i8042_install_filter
symbol could not be loaded.This commit fixes this by exiting from module_init with a return code
of 0 if no controller is found. It also adds a i8042_present bool to
make the module_exit function a no-op in this case and also adds a
check for i8042_present to the exported i8042_command function.The latter i8042_present check should not really be necessary because
when builtin that function can already be used on systems without
an i8042 controller, but better safe then sorry.Reported-and-tested-by: Marius Iacob

Pull more parisc updates from Helge Deller:
- During this merge window O_NONBLOCK was changed to become 000200000,
but we missed that the syscalls timerfd_create(), signalfd4(),
eventfd2(), pipe2(), inotify_init1() and userfaultfd() do a strict
bit-wise check of the flags parameter.To provide backward compatibility with existing userspace we
introduce parisc specific wrappers for those syscalls which filter
out the old O_NONBLOCK value and replaces it with the new one.- Prevent HIL bus driver to get stuck when keyboard or mouse isn't
attached- Improve error return codes when setting rtc time

When starting a HP machine with HIL driver but without an HIL keyboard
or HIL mouse attached, it may happen that data written to the HIL loop
gets stuck (e.g. because the transaction queue is full). Usually one
will then have to reboot the machine because all you see is and endless
output of:
Transaction add failed: transaction already queued?In the higher layers hp_sdc_enqueue_transaction() is called to queued up
a HIL packet. This function returns an error code, and this patch adds
the necessary checks for this return code and disables the HIL driver if
further packets can't be sent.Tested on a HP 730 and a HP 715/64 machine.

For a Hyper-V vmbus, the size of the ringbuffer has two requirements:
1) it has to take one PAGE_SIZE for the header
2) it has to be PAGE_SIZE aligned so that double-mapping can work
VMBUS_RING_SIZE() could calculate a correct ringbuffer size which
fulfills both requirements, therefore use it to make sure vmbus work
when PAGE_SIZE != HV_HYP_PAGE_SIZE (4K).Note that since the argument for VMBUS_RING_SIZE() is the size of
payload (data part), so it will be minus 4k (the size of header when
PAGE_SIZE = 4k) than the original value to keep the ringbuffer total
size unchanged when PAGE_SIZE = 4k.Signed-off-by: Boqun Feng
