We get the following warning with the driver is compiled in: WARNING: modpost: Found 1 section mismatch(es). To see full details build your kernel with: 'make CONFIG_DEBUG_SECTION_MISMATCH=y' With CONFIG_DEBUG_SECTION_MISMATCH enabled, the details are reported: WARNING: vmlinux.o(.text+0x55d014): Section mismatch in reference from the function fsl_guts_probe() to the function .init.text:of_flat_dt_get_machine_name() The function fsl_guts_probe() references the function __init of_flat_dt_get_machine_name(). This is often because fsl_guts_probe lacks a __init annotation or the annotation of of_flat_dt_get_machine_name is wrong. This patch stashes the machine name during fsl_guts_init initcall to fix the above warnings.
