Jingoo Han 0a16ee633a extcon: Remove unnecessary OOM messages
The site-specific OOM messages are unnecessary, because they
duplicate the MM subsystem generic OOM message. The following
checkpatch warning is also removed.

  WARNING: Possible unnecessary 'out of memory' message

Chanwoo Choi 42d7d7539a extcon: Simplify extcon_dev_register() prototype by removing unnecessary parameter
This patch remove extcon_dev_register()'s second parameter which means
the pointer of parent device to simplify prototype of this function.
So, if extcon device has the parent device, it should set the pointer of
parent device to edev.dev.parent in extcon device driver instead of in
extcon_dev_register().

Features of 'Dock-Smart device'

- Support charging and data connection through micro-usb port

Chanwoo Choi 0e2738f59c 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
is N/A.
