Re: [PATCH 1/2 v2] i2c: cros-ec-tunnel: Add of match table
Doug posted a patch [0] to fix the issue you are reporting but it was not picked. I tested that the patch applies on top of linux-next + the latest cros_ec cleanups (that includes a patch for this i2c driver and was taken by Lee. So I think is safe for you take Doug's patch through your tree since it seems to not cause any conflict with the mfd tree. OK, thanks for the heads up. I picked it. signature.asc Description: Digital signature

[PATCH 1/2 v2] i2c: cros-ec-tunnel: Add of match table
To enable the cros-ec-tunnel driver to be auto-loaded when build as a
module add an of match table (and export it) to match the modalias
information passed on to userspace as the Cros EC MFD driver registers
the MFD subdevices with an of_compatibility string.
