Merge branch 'i2c/for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
"I2C has:
- using defines for bus speeds to avoid mistakes in hardcoded values;
lots of small driver updates because of that. Thanks, Andy!
- API change: i2c_setup_smbus_alert() was renamed to
i2c_new_smbus_alert_device() and returns ERRPTR now. All in-tree
users have been converted
- in the core, a rare race condition when deleting the cdev has been
fixed. Thanks, Kevin!
- lots of driver updates. Thanks, everyone!
I also want to mention: The amount of review and testing tags given
was quite high this time. Thank you to these people, too. I hope we
can keep it like this!"
