From 7cc1b02f8f73fc0b5e1531a1e16b1c00819d5222 Mon Sep 17 00:00:00 2001 From: Darwin Rambo Date: Fri, 13 Dec 2013 12:57:26 -0800 Subject: [PATCH] i2c: Fix i2c speed command This corrects i2c core to interpret the value returned by i2c_set_bus_speed as a success indicator rather than the actual speed that was set. When i2c_set_bus_speed returns a failure code, the speed is unknown so the adapter speed is set to zero.
