staging: rt2860: change plain format of mac address to %pM in *printf()
There are many locations where MAC or BSSID is printed. The plain format
is used in such places. *printf() in kernel recognizes
%pM, %pMF and %pm format parameters to print out 6-byte array as MAC
address. This patch changes plain format to custom %pM which is widely
used in kernel.

Staging: batman-adv: Always synchronize rcu's on module shutdown
During the module shutdown procedure in batman_exit(), a rcu callback is
being scheduled (batman_exit -> hardif_remove_interfaces ->
hardif_remove_interfae -> call_rcu). However, when the kernel unloads
the module, the rcu callback might not have been executed yet, resulting
in a "unable to handle kernel paging request" in __rcu_process_callback
afterwards, causing the kernel to freeze.
The synchronize_net and synchronize_rcu in mesh_free are currently
called before the call_rcu in hardif_remove_interface and have no real
effect on it.
Therefore, we should always flush all rcu callback functions scheduled
during the shutdown procedure using synchronize_net. The call to
synchronize_rcu can be omitted because synchronize_net already calls it.
This is for the Asahi Kasei AK8975 3-axis magnetometer. It resides within
the magnetometer section of the IIO subsystem, and implements the raw
magn_x,y,z_raw attributes, as well as magn_x,y,z_scale attributes for
converting to Gauss.
Changed to use the magn_x,y,z_scale attributes, and made those attributes
give the scale factor to conert to Gauss. Also applied more fixes from
feedback.
Keeping mode as an unsigned long. I'm going to add proper power management
at some point anyway, which would deprecate this attribute.

staging: hv: Convert vmbus driver interface function pointer table to constant
Convert vmbus driver interface function pointer table to constant
The vmbus interface functions are assigned to a constant - vmbus_ops.
Because the vmbus interface function pointer table is converted to a
constant variable -- vmbus_ops, the function GetChannelInterface(),
VmbusGetChannelInterface() and pointer GetChannelInterface are no longer
in use. The deprecated function's work is done by the initialization of
the newly added constant variable vmbus_ops.
I created the new constant variable vmbus_ops and removed the deprecated
function pointer GetChannelInterface in one patch.

Fix fb_defio bug in udlfb for multiple framebuffers

module to track changed areas of the framebuffer by page faults.
Standard fbdev applications that use mmap but that do not
report damage, may be able to work with this enabled.
Disabled by default because of overhead and other issues.
console Allow fbcon to attach to udlfb provided framebuffers. This
is disabled by default because fbcon will aggressively consume
the first framebuffer it finds, which isn't usually what the
user wants in the case of USB displays.
staging: udlfb: support for writing backup EDID to sysfs file
Support writing default/backup edid via /sys/class/graphics/fb?/edid
Writing a backup edid blob to the 'edid' file will cause udlfb to
attempt to re-read the edid from hardware.
If we still don't have a good edid, it will use the backup edid instead.
The intent is to 1) enable user-supplied edid
2) enable udev rules to backup the last known good edid
for a device, and then provide that edid as a backup for all future starts
staging: udlfb: enhance EDID and mode handling support
Enhance EDID and mode table handling
* Adds support for lower-end DL chips on higher-end monitors
* Adds support for using fbdev standard EDID parsing and handling
* Adds support for more dynamic reallocation of framebuffer, based on new EDID
Queries EDID from hardware with several retries then
queries DisplayLink chip for max pixel area via vendor descriptor.
Uses existing fbdev mode handling service funcations to build mode list
of common modes between adapter and monitor.
This enables lower-end chips (e.g. DL-125) to successfully pick a compatible
mode on higher end monitors (e.g. whose default mode is over 1280x1024).
Reallocate framebuffer if necessary in response to new max mode.
staging: udlfb: revamp reference handling to insure successful shutdown
Revamp reference handling and synchronization for unload/shutdown
Udlfb is a "virtual" framebuffer device that really exists on
two separate stacks: at the bottom of the framebuffer interface,
and on top of USB. During unload, there's no guarantee which
one will tear down first. So reference counting must be solid
to handle all possibilities and not access anything once its gone.
Previously returned multiple values, which goes against sysfs guidelines.
Had been used for debugging to figure out which of the multiple
fbdev interfaces an app was using, but log file messages are sufficient.
staging: udlfb: fbdev character read and write support
Restore fbdev character read and write support
Enables access to the framebuffer from simple reads and writes
to /dev/fb0 (or fb1, ...). Low performance, because of extra copy
and because udlfb must scan every pixel for changes. But very
useful for testing and simple image display, etc.
