Staging: xgifb: Remove LCDA detection in xgifb_probe().
The piece of code that checks for LCDA in xgifb_probe() just checks for some
register values but doesn't really do anything in response to them (the actions
that should be executed are commented).
As nothing is really being done, the code can be safely removed.

staging: vt6656: iwctl: fix up spacing around operators
A few cases were missed in my previous cleanup, this takes care of the
last cases of missing space (or too much space (as in a newline))
around operators ('=', '==', ',', '<').
This patch improves mapping performance in zsmalloc by getting
usage information from the user in the form of a "mapping mode"
and using it to avoid unnecessary copying for objects that span
pages.
This patch replaces the page table assisted object mapping
method, which has x86 dependencies, with a arch-independent
method that does a simple copy into a temporary per-cpu
buffer.
While a copy seems like it would be worse than mapping the pages,
tests demonstrate the copying is always faster and, in the case of
running inside a KVM guest, roughly 4x faster.
zcache is enabled only if one of CONFIG_CLEANCACHE and CONFIG_FRONTSWAP is
enabled, see the Kconfig:
depends on (CLEANCACHE || FRONTSWAP) && CRYPTO=y && X86
So, we can remove the check in the source code

The driver assumes that in 13bit mode the 16bit value has
to be shifted to the right by 3 bits. This is not true, in
both 16bit and 13bit mode the MSB is at the same position.
Currently the driver returns a temperature of 194 degrees
Celsius in 13bit mode and 24 degrees Celsius in 16bit mode.
Fix this by using the same algorithm for 16bit and 13bit
mode and by just masking out the lower three bits in 13bit
mode.

The dev_attr list is initialized in __iio_add_event_config_attrs which
is called only when indio_dev->channels is true. Nevertheless the list
is used unconditionally later in iio_device_register_eventset which
results in a NULL pointer exception. To fix this unconditionally
initialize the list in iio_device_register_eventset.

iio: iio_buffer_register: Use correct channel when calculating masklength
The channel set assigned to the iio device is not necessarily the same has the
channel set passed to iio_buffer_register. So to avoid possible complications
always work with the channel set pass to iio_buffer_register and ignore the
channel set assigned to the iio device.

The name sysfs attribute is the same for all triggers, so there is no need to
register them dynamically at runtime. Create a attribute group for it and set it
up for the bus attribute group. This also avoids a possible race condition
where the uevent for the device is sent before the name sysfs attribute has been
added.
