2dc1158137 of/device: Replace struct of_device with struct platform_device
of_device is just an alias for platform_device, so remove it entirely.  Also
replace to_of_device() with to_platform_device() and update comment blocks.

This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.

ab265d5cdd docbook: use IDs as filenames to support multiple books
I'm trying to generate a <set> of <book>s in docbook for wireless to
link together all the cfg80211 and mac80211 documentation.

However, docbook will generate "re01.html" anew for each book for the
first <refentry>, presumably due to a bug in the stylesheets.

An effective workaround is to use IDs for the filenames, which makes
them more descriptive as well, e.g.  API-enum-ieee80211-band.html.

f90ebd9e98 drm_fb_helper: Preserve capability to use atomic kms
Commit 5349ef3127 (drm/fb: fix
FBIOGET/PUT_VSCREENINFO pixel clock handling) changed the logic of
when a pixclock was valid vs invalid.

The atomic kernel mode setting used by the kernel debugger relies upon
the drm_fb_helper_check_var() to always return -EINVAL.  Until a
better solution exists, this behavior will be restored.

c924b934d0 i915: when kgdb is active display compression should be off
If the HW compression is left on, the call backs from the HW will
crash the kernel.  The only time this code is called is when kernel
mode setting is in use with kgdb and the kdb shell.

The atomic display pipe handler callback will reset everything when
kgdb restores kernel to the run state.

d219adc122 fb: add hooks to handle KDB enter/exit
Add fb ops to handle enter/exit of the kernel debugger.  If present, the
fb core will register them with KGDB and they'll be called when the
debugger is entered and exited.  The new functions are responsible for
switching to an appropriate debug framebuffer and restoring the
interrupted state at exit time.

81d4450732 vt,console,kdb: automatically set kdb LINES variable
The kernel console interface stores the number of lines it is
configured to use. The kdb debugger can greatly benefit by knowing how
many lines there are on the console for the pager functionality
without having the end user compile in the setting or have to
repeatedly change it at run time.

3fa43aba08 debug_core,kdb: fix crash when arch does not have single step
When an arch such as mips and microblaze does not implement either HW
or software single stepping the debug core should re-enter kdb.  The
kdb code will properly ignore the single step operation.  Attempting
to single step the kernel without software or hardware support causes
unpredictable kernel crashes.

6d855b1d83 gdbstub: do not directly use dbg_reg_def[] in gdb_cmd_reg_set()
Presently the usable registers definitions on x86 are not contiguous
for kgdb.  The x86 kgdb uses a case statement for the sparse register
accesses.  The array which defines the registers (dbg_reg_def) should
not be used directly in order to safely work with sparse register
definitions.

Specifically there was a problem when gdb accesses ORIG_AX, which is
accessed only through the case statement.

This patch encodes register memory using the size information provided
from the debugger which avoids the need to look up the size of the
register.  The dbg_set_reg() function always further validates the
inputs from the debugger.
