Axel Lin 2429d86386 mfd: max77693: Init max77693->dev before using it
Current code uses max77693->dev in the dev_err call before setting it to
&i2c->dev. Fix it.

This patch also includes below cleanups:
 - Move checking pdata earlier and show dev_err if no platform data found.
 - Remove unnecessary err_regmap goto label.
 - Unregister i2c devices if regmap init for muic fails.

Chanwoo Choi b186b12487 mfd: MAX77693: Fix NULL pointer error when initializing irqs
This patch initialize register map of MUIC device because mfd driver
of Maxim MAX77693 use regmap-muic instance of MUIC device when irqs of
Maxim MAX77693 is initialized before call max77693-muic probe() function.

Mark Brown 0848c94fb4 mfd: core: Push irqdomain mapping out into devices
Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties.  This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern.  There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.

Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts.  The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.

Axel Lin ff2b7ac6f6 mfd: Fix max77693 irq leak and wrong kfree call
We need to call max77693_irq_exit() in max77693_i2c_probe error patch and
max77693_i2c_remove.

Current code already uses devm_kzalloc() to allocate memory for max77693.
Thus we should not call kfree(max77693), otherwise we got double free.

Now this driver is using regmap APIs, the iolock mutex is not used and can be
removed.
