drivers/misc/ioc4.c: fix section mismatch / race condition
Fix this section mismatch:
WARNING: drivers/misc/ioc4.o(.data+0x144): Section mismatch in reference from the variable ioc4_load_modules_work to the function .devinit.text:ioc4_load_modules()
The variable ioc4_load_modules_work references
the function __devinit ioc4_load_modules()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
This one is potentially fatal; by the time ioc4_load_modules is invoked
it may already have been freed. For that reason ioc4_load_modules_work
can't be turned to __devinitdata but also because it's referenced in
ioc4_exit.
