The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

There is no in-tree machine that provides a struct twl4030_platform_data
since commit e92fc4f04a34 ("ARM: OMAP2+: Drop legacy board file for
LDP"). So assume dev_get_platdata() returns NULL in twl_probe() and
simplify accordingly.

If twl4030_exit_irq() returns an error, the effect is that the caller
(twl_remove()) forwards the error to the i2c core without unregistering
its dummy slave devices. This only makes the i2c core emit another
error message and then it still removes the device.

In this situation it doesn't make sense to abort the remove cleanup and not
unregister the slave devices. So do that. Then return value is actually
unused and twl4030_exit_irq() can better be changed to return no value at
all.

This function returns 0 unconditionally, so there is no benefit in
returning a value at all and make the caller do error checking.

Also the caller (twl_remove()) cannot do anything sensible with an error
code. Passing it up the call stack isn't a good option because the i2c core
ignores error codes (apart from emitting an error message).

Since commit 6e2bd956936 ("i2c: omap: Use noirq system sleep pm ops to idle device for suspend")
on gta04 we have handle_twl4030_pih() called in situations where pm_runtime_get()
in i2c-omap.c returns -EACCES.

This happens when we wakeup via something behing twl4030 (powerbutton or rtc
alarm). This goes on for minutes until the system is finally resumed.
Disable the irq on suspend and enable it on resume to avoid
having i2c access problems when the irq registers are checked.
