This reverts commit c3dfefa0a6d235bd465309e12f4c56ea16e71111. gmbus in 3.4 has simply too many known issues: - gmbus is too noisy, we need to rework the logging: https://bugs.freedesktop.org/show_bug.cgi?id=48248 - zero-lenght writes cause an OOPS, and they are userspace-triggerable: https://lkml.org/lkml/2012/3/30/176 - same for zero-lenght reads: https://bugs.freedesktop.org/show_bug.cgi?id=48269 We can try again for 3.5.
