 "A few late-arriving fixes, plus two more significant changes that were
  *almost* ready at the beginning of the merge window:

   - A new document on debugging techniques from Sebastian Fricke

   - A clarification on MODULE_LICENSE terms meant to head off the sort
     of confusion that led to the recent Tuxedo Computers mess"

* tag 'docs-6.13-2' of git://git.lwn.net/linux:
  docs: Add debugging guide for the media subsystem
  docs: Add debugging section to process
  docs/licensing: Clarify wording about "GPL" and "Proprietary"
  docs: core-api/gfp_mask-from-fs-io: indicate that vmalloc supports GFP_NOFS/GFP_NOIO
  Documentation: kernel-doc: enumerate identifier *type*s
  Documentation: pwrseq: Fix trivial misspellings
  Documentation: filesystems: update filename extensions

Provide a guide for developers on how to debug code with a focus on the
media subsystem. This document aims to provide a rough overview over the
possibilities and a rational to help choosing the right tool for the
given circumstances.

The omap4 camera driver has seen no progress since forever, and
now OMAP4 support has also been dropped from u-boot (1). So it is
time to retire this driver.

form of jiffies.

Replace 'jiffie' by 'jiffy'. No functional change.

Add support for the Extron DA HD 4K Plus series of 4K HDMI
Distrubution Amplifiers (aka HDMI Splitters).

These devices support CEC and this driver adds support for the
CEC protocol for both the input and all outputs (2, 4 or 6 outputs,
depending on the model).

It also exports the EDID from the outputs and allows reading and
setting the EDID of the input.
