[PATCH 14/21] eeprom: at24: provide and use at24_base_client_dev()

From: Bartosz Golaszewski
Date: Mon Mar 19 2018 - 05:19:58 EST


Use a helper function for accessing the device struct of the base
i2c client. This routine is named in a way that reflects its purpose
unlike the previously hand-coded dereferencing.
