Here are some issues you may run into when porting something from 3.4 to 3.10:

  • __devexit is no longer used (or defined)
    • background: __devexit was an attribute used on certain driver routines. It was removed between 3.4 and 3.10, and should no longer be used
    • just remove the attribute from any functions it is used with


  • sysdev.h is gone, along with all it declared:
    • struct sys_device, struct sysdev_attribute

  • arch/arm/include/asm/hardware/gic.h was moved to include/linux/irqchip/arm-gic.h
    • change #include <asm/hardware/gic.h> to #include <linux/irqchip/arm-gic.h>
