[Wolfram Sang]

[-- Attachment #1: Type: text/plain, Size: 1325 bytes --]

Linus,

I2C has a MAINTAINERS update for you, so people will be immediately
pointed to the right person for this previously orphaned driver. And one
of Arnd's build warning fixes for a new driver added this cycle.

Please pull.

Thanks,

   Wolfram

I've pulled it, but please don't do this again.

The "New driver" rule has become pretty much historical, simply
because releases have been regular enough that it doesn't much make
much sense, and we just have't had the kinds of "basic support"
drivers that make sense pushing out as early as possible just to get
people able to use a machine at all. So in practice, the "new driver"
rule has become a "new ID or quirk" rule.

The nVidia i2c support doesn't sound so special that it couldn't have
waited until the merge window.

[Wolfram Sang]

[-- Attachment #1: Type: text/plain, Size: 2586 bytes --]

Linus,

I2C has one bugfix (qcom-geni driver), one arch enablement (i2c-omap driver, no
code change), and a new driver (nvidia-gpu) this time.

I hope the rc1 rule still applies for this new driver. It consists of the I2C
master part and UCSI client part which has the needed ack from Heikki.

Please pull.

Thanks,

   Wolfram

Linus,

welcome back! I hope the time off was good for you.

I2C has not so much stuff this time. Mostly driver enablement for new
SoCs, some driver bugfixes, and some cleanups.

Please pull.
