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.

[ Upstream commit 32cf3a610c35cb21e3157f4bbf29d89960e30a36 ]

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.

[ 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.

malicious device (or USB descriptor fuzzer) to trigger a NULL-pointer

commit ba9a103f40fc4a3ec7558ec9b0b97d4f92034249 upstream.

The driver was issuing synchronous uninterruptible control requests
without using a timeout. This could lead to the driver hanging on probe
due to a malfunctioning (or malicious) device until the device is
physically disconnected. While sleeping in probe the driver prevents
other devices connected to the same hub from being added to (or removed
from) the bus.

The USB upper limit of five seconds per request should be more than
enough.

commit ba9a103f40fc4a3ec7558ec9b0b97d4f92034249 upstream.

The driver was issuing synchronous uninterruptible control requests
without using a timeout. This could lead to the driver hanging on probe
due to a malfunctioning (or malicious) device until the device is
physically disconnected. While sleeping in probe the driver prevents
other devices connected to the same hub from being added to (or removed
from) the bus.

The USB upper limit of five seconds per request should be more than
enough.
