| Subject: can: c_can: don't indicate triple sampling support for D_CAN |

| 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. |
