Henrik Kretzschmar 872c1b14e7 mfd: Section cleanup of 88pm860x driver 
This patch fixes three section mismatches.

WARNING: drivers/mfd/88pm860x.o(.text+0x12): Section mismatch in
reference from the function pm860x_device_exit() to the function
.devexit.text:device_irq_exit()
The function pm860x_device_exit() references a function in an exit
section.
Often the function device_irq_exit() has valid usage outside the exit
section
and the fix is to remove the __devexit annotation of device_irq_exit.

WARNING: drivers/mfd/88pm860x.o(.text+0xb0): Section mismatch in
reference from the function pm860x_device_init() to the function
.devinit.text:device_8606_init()
The function pm860x_device_init() references
the function __devinit device_8606_init().
This is often because pm860x_device_init lacks a __devinit
annotation or the annotation of device_8606_init is wrong.

WARNING: drivers/mfd/88pm860x.o(.text+0xbe): Section mismatch in
reference from the function pm860x_device_init() to the function
.devinit.text:device_8607_init()
The function pm860x_device_init() references
the function __devinit device_8607_init().
This is often because pm860x_device_init lacks a __devinit
annotation or the annotation of device_8607_init is wrong.
