This patch cannot be applied to the kernel version 4.9, because the M-CAN driver in this kernel does not support M-CAN controllers with V3.1.x or V3.2.x, only 3.0.x is supported. Support for newer versions than 3.0.x was added in commit b03cfc5bb0e11f88988e5da2805867e468d03ca1, somewhere between v4.11-rc7 and v4.12-rc1.
