Subject: [PULL REQUEST] i2c for 5.1

Linus,

The I2C pull request contains this time:

* the I2C core gained helpers to assist drivers in handling their
  suspended state, and drivers were converted to use it
* two new fault-injectors for stress-testing
* bigger refactoring and feature improvements for the ocores, sh_mobile,
  and tegra drivers
* platform_data removal for the at24 EEPROM driver
* and various improvements and bugfixes all over the subsystem

Please pull.

Thanks,

   Wolfram
