From f1a640c5dc701f661d4359d86601a845a41858d0 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Mon, 19 Mar 2018 10:17:14 +0100 Subject: eeprom: at24: provide and use at24_base_client_dev() 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.
