Linus Torvalds 0d1d44032f Merge tag 'fbdev-for-6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/linux-fbdev
Pull fbdev updates from Helge Deller:
 "The Termius 10x18 console bitmap font has been added. It is good
  match for modern 13-16 inch laptop displays with resolutions like
  1280x800 and 1440x900 pixels.

  The gbefb and tcx.c drivers got some fixes to restore X11 support,
  pxafb was not actually clamping input values and the ssd1307fb driver
  leaked memory in the failure path.

  The other patches convert some common drivers to use dev_info() and
  dev_dbg() instead of printk(). Summary:

  Framework updates:
   - fonts: Add Terminus 10x18 console font [Neilay Kharwadkar]

  Driver fixes:
   - gbefb: fix to use physical address instead of dma address [René Rebe]
   - tcx.c fix mem_map to correct smem_start offset [René Rebe]
   - pxafb: Fix multiple clamped values in pxafb_adjust_timing [Thorsten Blum]
   - ssd1307fb: fix potential page leak in ssd1307fb_probe() [Abdun Nihaal]

  Cleanups:
   - vga16fb: Request memory region [Javier Garcia]
   - vga16fb: replace printk() with dev_*() in probe [Vivek BalachandharTN]
   - vesafb, gxt4500fb, tridentfb: Use dev_dbg() instead of printk() [Javier Garcia]
   - i810: use dev_info() [Shi Hao]"

Linux kernel
============

The Linux kernel is the core of any Linux operating system. It manages hardware,
system resources, and provides the fundamental services for all other software.

Quick Start
-----------

* Report a bug: See Documentation/admin-guide/reporting-issues.rst
* Get the latest kernel: https://kernel.org
* Build the kernel: See Documentation/admin-guide/quickly-build-trimmed-linux.rst
* Join the community: https://lore.kernel.org/

Essential Documentation
-----------------------

All users should be familiar with:

* Building requirements: Documentation/process/changes.rst
* Code of Conduct: Documentation/process/code-of-conduct.rst
* License: See COPYING

Documentation can be built with make htmldocs or viewed online at:
https://www.kernel.org/doc/html/latest/
