staging: unisys: visorbus: Remove notifier-related code from visorbus

When this functionality was first implemented, visorchipset and visorbus
were separate drivers, which necessitated a registration mechanism for
them to communicate.  More-recently, visorchipset and visorbus were
combined into a single driver, and now exist as separate source files
within the same driver, known as 'visorbus'.  This eliminated the need

A kernel timer is now used as the vehicle to periodically call the

workqueue.

This simplifies a lot of things by making periodic_work.c and
periodic_work.h no longer necessary.  This change also means that the
channel_interrupt() callbacks registered by visor drivers (via
visorbus_register_visor_driver()) will now be called in atomic context
(i.e., canNOT sleep) rather than kernel thread context (CAN sleep).
Fortunately this did NOT necessitate any change to the existing
channel_interrupt() callbacks, because none of them ever perform any
operations that would be invalid in atomic context.

android: binder: Remove deprecated create_singlethread_workqueue

The workqueue is being used to run deferred work for the android binder.

The "binder_deferred_workqueue" queues only a single work item and hence
does not require ordering. Also, this workqueue is not being used on a
memory recliam path. Hence, the singlethreaded workqueue has been
replaced with the use of system_wq.

System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.

staging: ks7010: Delete unnecessary assignments for buffer variables

A few variables were assigned a null pointer despite of the detail
that they were immediately reassigned by the following statement.
Thus remove such unnecessary assignments.

8 years agostaging: ks7010: Delete unnecessary checks before the function call "kfree"
Markus Elfring [Sun, 17 Jul 2016 11:14:57 +0000 (13:14 +0200)]
staging: ks7010: Delete unnecessary checks before the function call "kfree"

The kfree() function tests whether its argument is NULL and then
returns immediately. Thus the test around the calls is not needed.

This issue was detected by using the Coccinelle software.
