The various devm_ functions allocate memory that is released when a driver
detaches. This patch uses these functions for data that is allocated in

At the same time, this fixes two faults. First, mdev, the result of
kzalloc, was never freed. Second, on failure of ioremap, 0 was returned.
This has been replaced by -EBUSY, which was the failure value for the call
to request_mem_region, with which the call to ioremap has been combined.
The warning message on failure of ioremap is dropped, because
devm_request_and_ioremap already gives such messages on failure.
Finally, the initial call to platform_get_resource is moved closer to the
call to devm_request_and_ioremap, which takes care of checking whether its
result is NULL, implying that a test on the result of this call to
platform_get_resource is not needed.

extcon: max77693: Fix bug when detecting MHL/Dock-Audio with USB/TA cable
This patch fix bug that muic couldn't detect MHL/Dock-Audio with USB/TA
cable on exception situation. I explain detail case on following:
When MHL(with USB/TA cable) or Dock-Audio with USB/TA cable is attached,
the MUIC device happen following two interrupt.
- 'MAX77693_MUIC_IRQ_INT1_ADC' for detecting MHL/Dock-Audio.
- 'MAX77693_MUIC_IRQ_INT2_CHGTYP' for detecting USB/TA cable connected to
MHL/Dock-Audio. Always, happen eariler MAX77693_MUIC_IRQ_INT1_ADC interrupt
than MAX77693_MUIC_IRQ_INT2_CHGTYP interrupt.
If user attach MHL with USB/TA cable and immediately detach MHL with USB/TA
cable before MAX77693_MUIC_IRQ_INT2_CHGTYP interrupt is happened, USB/TA
connected to MHL cable remain connected state to target. But USB/TA connected
to MHL cable isn't connected to target. user be faced with unusual action.
So, driver should check this situation in spite of that, previous charger type
