commit 3c2bf173501652fced1d058834e9c983d295b126 upstream.
When CAN_FLEXCAN=y and M5441x is not set/enabled, there are build errors in coldfire/device.c:
../arch/m68k/coldfire/device.c:595:26: error: 'MCFFLEXCAN_BASE0' undeclared here (not in a function); did you mean 'MCFDMA_BASE0'? 595 | .start = MCFFLEXCAN_BASE0, ../arch/m68k/coldfire/device.c:596:43: error: 'MCFFLEXCAN_SIZE' undeclared here (not in a function) 596 | .end = MCFFLEXCAN_BASE0 + MCFFLEXCAN_SIZE, ../arch/m68k/coldfire/device.c:600:26: error: 'MCF_IRQ_IFL0' undeclared here (not in a function); did you mean 'MCF_IRQ_I2C0'? 600 | .start = MCF_IRQ_IFL0, ../arch/m68k/coldfire/device.c:605:26: error: 'MCF_IRQ_BOFF0' undeclared here (not in a function); did you mean 'MCF_IRQ_I2C0'? 605 | .start = MCF_IRQ_BOFF0, ../arch/m68k/coldfire/device.c:610:26: error: 'MCF_IRQ_ERR0' undeclared here (not in a function); did you mean 'MCF_IRQ_I2C0'? 610 | .start = MCF_IRQ_ERR0,
Protect the FLEXCAN code blocks by checking if MCFFLEXCAN_SIZE is defined.
