[ Upstream commit a69ce592cbe0417664bc5a075205aa75c2ec1273 ]

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.

<title>Input: synaptics-rmi4 - handle reset delay when using SMBus trsnsport</title>

[ Upstream commit 5030b2fe6aab37fe42d14f31842ea38be7c55c57 ]

Touch controllers need some time after receiving reset command for the
firmware to finish re-initializing and be ready to respond to commands
from the host. The driver already had handling for the post-reset delay
for I2C and SPI transports, this change adds the handling to
SMBus-connected devices.

SMBus devices are peculiar because they implement legacy PS/2
compatibility mode, so reset is actually issued by psmouse driver on the
associated serio port, after which the control is passed to the RMI4
driver with SMBus companion device.

Note that originally the delay was added to psmouse driver in
92e24e0e57f7 ("Input: psmouse - add delay when deactivating for SMBus
mode"), but that resulted in an unwanted delay in "fast" reconnect
handler for the serio port, so it was decided to revert the patch and
have the delay being handled in the RMI4 driver, similar to the other
transports.

<id>urn:sha1:211f71c1c0a7e7934b4b176bcd35c687c6505f11</id>
<content type='text'>
commit e2cb5cc822b6c9ee72c56ce1d81671b22c05406a upstream.

When the SMBus connection is attempted psmouse_smbus_init() sets
the fast_reconnect pointer to psmouse_smbus_reconnecti(). If SMBus
initialization fails, elantech_setup_ps2() and synaptics_init_ps2() will
fallback to PS/2 mode, replacing the psmouse private data. This can cause
issues on resume, since psmouse_smbus_reconnect() expects to find an
instance of struct psmouse_smbus_dev in psmouse-&gt;private.

The issue was uncovered when in 92e24e0e57f7 ("Input: psmouse - add
delay when deactivating for SMBus mode") psmouse_smbus_reconnect()
started attempting to use more of the data structure. The commit was
since reverted, not because it was at fault, but because there was found
a better way of doing what it was attempting to do.

Fix the problem by resetting the fast_reconnect pointer in psmouse
structure in elantech_setup_ps2() and synaptics_init_ps2() when the PS/2
mode is used.

commit 8980f190947ba29f23110408e712444884b74251 upstream.

The recent change of -funsigned-char causes additions of negative
numbers to become additions of large positive numbers, leading to wrong
calculations of mouse movement. Change these casts to be explicitly
signed, to take into account negative offsets.

commit 754ff5060daf5a1cf4474eff9b4edeb6c17ef7ab upstream.

The AlpsPS/2 code previously relied on the assumption that `char` is a
signed type, which was true on x86 platforms (the only place where this
driver is used) before kernel 6.2. However, on 6.2 and later, this
assumption is broken due to the introduction of -funsigned-char as a new
global compiler flag.

Fix this by explicitly specifying the signedness of `char` when sign
extending the values received from the device.
