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.
