commit 20f722f4a9ace367fca4417ab7ecb4a75050f7ef Author: Furquan Shaikh furquan@chromium.org Date: Tue Dec 13 21:50:32 2016 -0800
drivers/i2c: Pass in i2c_generic_config into i2c_generic_fill_ssdt
Remove any assumptions required for the drivers using i2c_generic to have drivers_i2c_generic_config structure at the start of the driver config. Instead pass in a pointer to drivers_i2c_generic_config from the calling driver.
