Some displays from AUO have a so called in-cell touchscreen, meaning it
is built directly into the display unit.Touchdata is gathered through PIXCIR Tango-ICs and processed in an
Atmel ATmega168P with custom firmware. Communication between the host
system and ATmega is done via I2C.Devices using this touch solution include the Dell Streak5 and the family
of Qisda ebook readers.The driver reports single- and multi-touch events including touch area
values.Signed-off-by: Heiko Stuebner

The Cintiq 24HD has three LEDs on the left side of the tablet and
three LEDs on the right side of the tablet. Switching to LED 0,
1, or 2 will enable the top, middle, or bottom LED for the respective
side. Switching to LED 3 turns off the LEDs on the respective side.Signed-off-by: Jason Gerecke

Adds support for the Cintiq 24HD. There are two quirks about this
model that haven't been seen in prior tablets. First, a second
touch ring is present on this display; it is being exposed via the
ABS_THROTTLE axis. Second, three capacitive buttons at the top of
the unit are available; though physically a touch strip, we report
the use of these buttons with generic KEY_ events.Signed-off-by: Jason Gerecke

This driver adds support for Sharp's GP2AP002A00F proximity sensor. The
proximity is measured as a binary switch, i.e. an object is either
detected or not detected. Hence, this driver is implemented as a switch
that reports SW_FRONT_PROXIMITY.Reviewed-by: Datta Shubhrajyoti

Having module device table based on PNP id produces the following warning:
CC drivers/input/touchscreen/htcpen.o
drivers/input/touchscreen/htcpen.c:50: warning: 'pnp_ids' defined but not usedThis happens because it is not a PNP driver, bit rather ISA driver and
pnp_ids table is not used anywhere. To fix this issue let's switch to
DMI-based module table instead,Reported-by: Axel Lin

There exist tilt switches that simply report their tilt-state via
some gpios. The number and orientation of their axes can vary
depending on the switch used and the build of the device. Also two
or more one-axis switches could be combined to provide multi-dimensional
orientation.One example of a device using such a switch is the family of Qisda
ebook readers, where the switch provides information about the
landscape / portrait orientation of the device. The example in
Documentation/input/gpio-tilt.txt documents exactly this one-axis
device.Signed-off-by: Heiko Stuebner

In ancient times it was necessary to manually initialize the bus field of an
spi_driver to spi_bus_type. These days this is done in spi_driver_register(),
so we can drop the manual assignment.The patch was generated using the following coccinelle semantic patch:
//

identifier _driver;

struct spi_driver _driver = {
.driver = {
- .bus = &spi_bus_type,

virtio-pci: make reset operation safer
virtio-mmio: Correct the name of the guest features selector
virtio: add HAS_IOMEM dependency to MMIO platform bus driver -
virtio pci device reset actually just does an I/O
write, which in PCI is really posted, that is it
can complete on CPU before the device has received it.Further, interrupts might have been pending on
another CPU, so device callback might get invoked after reset.This conflicts with how drivers use reset, which is typically:
reset
unregister
a callback running after reset completed can race with
unregister, potentially leading to use after free bugs.Fix by flushing out the write, and flushing pending interrupts.
This assumes that device is never reset from
its vq/config callbacks, or in parallel with being
added/removed, document this assumption.Signed-off-by: Michael S. Tsirkin

eCryptfs: Extend array bounds for all filename chars
eCryptfs: Flush file in vma close
eCryptfs: Prevent file create race condition -
From mhalcrow's original commit message:
Characters with ASCII values greater than the size of
filename_rev_map[] are valid filename characters.
ecryptfs_decode_from_filename() will access kernel memory beyond
that array, and ecryptfs_parse_tag_70_packet() will then decrypt
those characters. The attacker, using the FNEK of the crafted file,
can then re-encrypt the characters to reveal the kernel memory past
the end of the filename_rev_map[] array. I expect low security
impact since this array is statically allocated in the text area,
and the amount of memory past the array that is accessible is
limited by the largest possible ASCII filename character.This patch solves the issue reported by mhalcrow but with an
implementation suggested by Linus to simply extend the length of
filename_rev_map[] to 256. Characters greater than 0x7A are mapped to
0x00, which is how invalid characters less than 0x7A were previously
being handled.Signed-off-by: Tyler Hicks

Dirty pages weren't being written back when an mmap'ed eCryptfs file was
closed before the mapping was unmapped. Since f_ops->flush() is not
called by the munmap() path, the lower file was simply being released.

The file creation path prematurely called d_instantiate() and
unlock_new_inode() before the eCryptfs inode info was fully
allocated and initialized and before the eCryptfs metadata was written
to the lower file.This could result in race conditions in subsequent file and inode
operations leading to unexpected error conditions or a null pointer
dereference while attempting to use the unallocated memory.https://launchpad.net/bugs/813146
