From 6d001e7df9e4b33b9be9bc4117091365b2ff1607 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin <Alexey.Brodkin@synopsys.com> Date: Wed, 11 Dec 2013 18:04:40 +0400 Subject: [PATCH] env_eeprom - fix bus recovery for "eeprom_bus_read" "env_eeprom_bus" is no longer in use (it was introduced in commit 548738b4d43af841ff58c787bce297ac6a8bf7d1 "cmd_eeprom: I2C updates"). As in "eeprom_bus_write" we just reset I2C bus with the one we saved in "old_bus".
