[GIT PULL] auxdisplay for 6.9-1

Hi Linus,

First PR from me as a maintainer of auxdisplay subsystem. Miguel retired and
nominated me as a successor (it appears that for the last a couple of years
I am appeared a main contributor to the subsystem), however I have no much time
for that, that's why the update in MAINTAINERS has 'Odd Fixes'. Nevertheless,
Geert agreed to help as the official reviewer. So far so good, the collection
of the code has been in Linux Next for a while with one reported issue that
had been addressed (and also stayed a couple of days in the Linux Next).
Please pull for v6.9-rc1.

Thanks,

With Best Regards,
Andy Shevchenko

----------------------------------------------------------------
auxdisplay for v6.9-1

* New driver for GPIO based 7-segment LED display (Chris Packham)

- auxdisplay: Add Maxim MAX6958/6959
- auxdisplay: hit,hd44780: use defines for GPIO flags
- auxdisplay: adjust example indentation and use generic node names

hd44780:
- Convert to platform remove callback returning void

ht16k33:
- Drop struct ht16k33_seg
- Switch to use line display character mapping
- Define a few helper macros
- Move ht16k33_linedisp_ops down
- Add default to switch-cases

img-ascii-lcd:
- Convert to platform remove callback returning void
- Make container_of() no-op for struct linedisp

linedisp:
- Allocate buffer for the string
- Add support for overriding character mapping
- Provide struct linedisp_ops for future extension
