From 94c87527f4e1ebf85936f707ec84ff458f3bbb00 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Fri, 22 Mar 2019 00:04:20 +0100 Subject: i2c: mt65xx: make bindings file name match the driver If we use the "i2c-" prefix for the binding documentation file name, then it should match the file name of the driver, if possible. It is possible for this driver, so rename it.
