[PATCH 3.16 179/204] can: c_can: don't indicate triple sampling support for D_CAN

From: Ben Hutchings
Date: Thu Dec 28 2017 - 12:40:18 EST


3.16.52-rc1 review patch. If anyone has any objections, please let me know.

------------------

From: Richard SchÃtz <rschuetz@xxxxxxxxxxxxxx>

commit fb5f0b3ef69b95e665e4bbe8a3de7201f09f1071 upstream.

The D_CAN controller doesn't provide a triple sampling mode, so don't set
the CAN_CTRLMODE_3_SAMPLES flag in ctrlmode_supported. Currently enabling
triple sampling is a no-op.
