From d8e0a86f9713689e35dc14f7184e85a13a2a9f4e Mon Sep 17 00:00:00 2001 From: Doug Anderson Date: Mon, 23 Jun 2014 14:20:06 -0700 Subject: i2c: cros_ec: Remove EC_I2C_FLAG_10BIT In pointed out that the 10-bit flag in the cros_ec_tunnel was useless. It went into a 16-bit flags field but was defined at (1 << 16). Since we have no 10-bit i2c devices on the other side of the tunnel on any known devices this was never a problem. Until we do it makes sense to remove this code. On the EC side the code to handle this flag was removed in .
