Input: synaptics - enable RMI on HP Envy 13-ad105ng

2020-04-02T13:28:16+00:00

commit 1369d0abe469fb4cdea8a5bce219d38cb857a658 upstream.

This laptop (and perhaps other variants of the same model) reports an
SMBus-capable Synaptics touchpad. Everything (including suspend and
resume) works fine when RMI is enabled via the kernel command line, so
let's add it to the whitelist.

Input: raydium_i2c_ts - fix error codes in raydium_i2c_boot_trigger()

2020-04-02T13:28:16+00:00

commit 32cf3a610c35cb21e3157f4bbf29d89960e30a36 upstream.

These functions are supposed to return negative error codes but instead
it returns true on failure and false on success.  The error codes are
eventually propagated back to user space.

Input: edt-ft5x06 - work around first register access error

2020-02-24T07:34:46+00:00

[ Upstream commit e112324cc0422c046f1cf54c56f333d34fa20885 ]

The EP0700MLP1 returns bogus data on the first register read access
(reading the threshold parameter from register 0x00):

    edt_ft5x06 2-0038: crc error: 0xfc expected, got 0x40

It ignores writes until then. This patch adds a dummy read after which
the number of sensors and parameter read/writes work correctly.

Input: synaptics - remove the LEN0049 dmi id from topbuttonpad list

2020-02-19T18:51:53+00:00

commit 5179a9dfa9440c1781816e2c9a183d1d2512dc61 upstream.

The Yoga 11e is using LEN0049, but it doesn't have a trackstick.

Thus, there is no need to create a software top buttons row.

However, it seems that the device works under SMBus, so keep it as part
of the smbus_pnp_ids.

Input: synaptics - switch T470s to RMI4 by default

commit bf502391353b928e63096127e5fd8482080203f5 upstream.

This supports RMI4 and everything seems to work, including the touchpad
buttons. So, let's enable this by default.

commit 97e24b095348a15ec08c476423c3b3b939186ad7 upstream.

The driver misses a check for devm_thermal_zone_of_sensor_register().
Add a check to fix it.

commit bcfcb7f9b480dd0be8f0df2df17340ca92a03b98 upstream.

The driver was checking the number of endpoints of the first alternate
setting instead of the current one, something which could be used by a
malicious device (or USB descriptor fuzzer) to trigger a NULL-pointer
dereference.

commit 3111491fca4f01764e0c158c5e0f7ced808eef51 upstream.

The driver was checking the number of endpoints of the first alternate
setting instead of the current one, something which could lead to the
driver binding to an invalid interface.

This in turn could cause the driver to misbehave or trigger a WARN() in
usb_submit_urb() that kernels with panic_on_warn set would choke on.
