Subject: [PATCH 4.9 05/16] can: rcar_canfd: rcar_canfd_channel_probe(): register the CAN device when fully ready
From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>
[ Upstream commit c5048a7b2c23ab589f3476a783bd586b663eda5b ]
Register the CAN device only when all the necessary initialization is
completed. This patch makes sure all the data structures and locks are
initialized before registering the CAN device.
