[PATCH] parisc: Make struct parisc_driver::remove() return void

[PATCH] parisc: Make struct parisc_driver::remove() return void

[Uwe Kleine-König]

The caller of this function (parisc_driver_remove() in
arch/parisc/kernel/drivers.c) ignores the return value, so better don't
return any value at all to not wake wrong expectations in driver authors.

The only function that could return a non-zero value before was
ipmi_parisc_remove() which returns the return value of
ipmi_si_remove_by_dev(). Make this function return void, too, as for all
other callers the value is ignored, too.

Also fold in a small checkpatch fix for:

WARNING: Unnecessary space before function pointer arguments
+	void (*remove) (struct parisc_device *dev);

This function is also used by ipmi_si_platform.c, so you can't change
this.

Did you see that I adapted ipmi_si_platform.c below? That is an instance
of "Make [ipmi_si_remove_by_dev] return void, too, as for all other
callers the value is ignored, too." (In ipmi_si_platform.c the return
value is used in a struct platform_driver::remove function. The value
returned there is ignored, see commit
e5e1c209788138f33ca6558bf9f572f6904f486d.)

Best regards
Uwe
