Subject[PATCH v3 00/11] fblog: Framebuffer kernel log driver v3

This is revision 3 of the fblog driver. This driver is a replacement for fbcon
for systems that do not want/need CONFIG_VT. It simply prints the kernel log to
all connected framebuffers. Previous versions are available here:

This patchset is against linux-next from last week (Wednesday or Thursday).

I've fixed all issues that were reported last week. They were all minor
- Changed EXPORT_SYMBOL to EXPORT_SYMBOL_GPL for exported fbdev functions
- Removed FBLOG_STR
- Added pr_fmt()
- Fixed two minor coding-style issues
- Fixed one possible subtle deadlock in device registration (switched locking

If you want to test it but don't want to disable CONFIG_VT, simply remove the
dependency to !VT of fblog. This will cause both fblog and fbcon to draw to the
framebuffers but both draw only on changes so it will still be possible to debug
and test fblog.

It would be nice if someone could tell me what tree this will go through or how
I can get it into linux-next as I have no idea who is maintaining fbcon. If
there are other major or minor issues, please tell me so I can work on them.

I am also working on improving the render-path by using dma-buf and partial
redraws like fbcon. Furthermore, I will add a panic-handler so fblog draws
oopses/panics to the framebuffers even though it is disabled. However, I want to
get this basic driver in before making it more complex and making review too

Thanks! Regards

fbcon: move update_attr() into separate source file
fbcon: move bit_putcs() into separate source file
fblog: new framebuffer kernel log dummy driver
fbdev: export get_fb_info()/put_fb_info()
fblog: register one fblog object per framebuffer
fblog: open fb on registration
fblog: allow selecting fbs via sysfs
fblog: cache framebuffer BLANK and SUSPEND states
fblog: register console driver
fblog: draw console to framebuffers
MAINTAINERS: add fblog entry
