[PULL REQUEST] i2c for 5.4

[Wolfram Sang]

[-- Attachment #1: Type: text/plain, Size: 1300 bytes --]

Linus,

Here is an I2C core fix to prevent a use-after-free in a rare error path
and an I2C ACPI addition to work around broken HW/firmware related to
touchscreens.

Please pull.

Thanks,

   Wolfram

[PULL REQUEST] i2c for 5.4

[Wolfram Sang]

[-- Attachment #1: Type: text/plain, Size: 1916 bytes --]

Linus,

this second pull request from I2C contains:

- make Lenovo Yoga C630 boot now that the dependencies are merged
- restore BlockProcessCall for i801, accidently removed in this merge
  window
- a bugfix for the riic driver
- an improvement to the slave-eeprom driver which should have been in
  the first pull request but sadly got lost in the process

And finally, my pull requests should be using utf-8 now.

Please pull.

Thanks,

   Wolfram

Well, a couple of happy users there...

Sorry, my template for pull-requests had bogus header overriding the
default utf-8 of my config. I fixed it now. Thanks for pointing it out.

Heh, no need to convince me, I am all for utf-8!

Christ. Will that thing _never_ die?

But the reason I'm actually replying is not to comment on the apparent
death-defying Amiga hardware scene, but to point out that you should
try to fix your email configuration:

This is all fine in the git repo, being proper utf-8 "Björn Ardö".

But your mutt setup doesn't seem to be using a proper utf-8 locale and
instead uses

  Content-Type: text/plain; charset=us-ascii
  Content-Disposition: inline

like it was the last century.

I don't know what the proper mutt incantation is to make it join the
modern world, but I'm sure one exists, and then your emails would get
names right too. Even if they are some funky Swedish ones with åäö.

(And no, don't use Latin1 - it may cover Swedish and German etc, but
you really want to go with proper utf-8 and be able to handle true
complex character sets, not just the Western European ones).

Linus,

I2C has this time:

- new driver for ICY, an Amiga Zorro card :)
- axxia driver gained slave mode support, NXP driver gained ACPI
- the slave EEPROM backend gained 16 bit address support
- and lots of regular driver updates and reworks

Please pull.

Thanks,

   Wolfram
