[ Upstream commit 255cdaf73412de13608fb776101402dca68bed2b ]
Since commit b6eba86030bf ("Input: edt-ft5x06 - add offset support for
ev-ft5726") offset-x and offset-y is supported. Devices using those
offset parameters don't support the offset parameter so we need to add
the NO_REGISTER check for edt_ft5x06_ts_get_defaults().
Fixes: b6eba86030bf ("Input: edt-ft5x06 - add offset support for ev-ft5726")

The Lenovo Thinkpad T470s I own has a different touchpad with "LEN007a"
instead of the already included PNP ID "LEN006c". However, my touchpad
seems to work well without any problems using RMI. So this patch adds the
other PNP ID.

MMS345L is another first generation touch screen from Melfas,
which uses the same registers as MMS152.
However, using I2C_M_NOSTART for it causes errors when reading:
i2c i2c-0: sendbytes: NAK bailout.
mms114 0-0048: __mms114_read_reg: i2c transfer failed (-5)
The driver works fine as soon as I2C_M_NOSTART is removed.

[ Upstream commit d5a5e5b5fa7b86c05bf073acc0ba98fa280174ec ]
Fix a use-after-free noticed by running with KASAN enabled. If
rmi_irq_fn() is run twice in a row, then rmi_f11_attention() (among
others) will end up reading from drvdata->attn_data.data, which was
freed and left dangling in rmi_irq_fn().
Commit 55edde9fff1a ("Input: synaptics-rmi4 - prevent UAF reported by
KASAN") correctly identified and analyzed this bug. However the attempted
fix only NULLed out a local variable, missing the fact that
drvdata->attn_data is a struct, not a pointer.
NULL out the correct pointer in the driver data to prevent the attention
functions from copying from it.

input_flush_device() should only be called once the struct file is being
released and no open descriptors remain, but evdev_flush() was calling
it whenever a file descriptor was closed.
This caused uploaded force-feedback effects to be erased when a process
did a dup()/close() on the event FD, called system(), etc.
Call input_flush_device() from evdev_release() instead.

commit ebc68cedec4aead47d8d11623d013cca9bf8e825 upstream.
The Acer Aspire 5738z has a button to disable (and re-enable) the
touchpad next to the touchpad.
When this button is pressed a LED underneath indicates that the touchpad
is disabled (and an event is send to userspace and GNOME shows its
touchpad enabled / disable OSD thingie).
So far so good, but after re-enabling the touchpad it no longer works.
The laptop does not have an external ps2 port, so mux mode is not needed
and disabling mux mode fixes the touchpad no longer working after toggling
it off and back on again, so lets add this laptop model to the nomux list.
