Sachin Kamat 68c9274d0f extcon: max8997: Fix incorrect error check and return value
irq_create_mapping() returns 0 if it fails to provide a valid irq number.
'ret' needs to be updated with a negative error code before returning from
probe to signal probe failure. While at it, also corrected the 'virq' type to
unsigned from signed.

Axel Lin 155cb06c89 extcon: Fix wrong index in max8997_extcon_cable[]
Currently, the index of "Dock-desk" and "Dock-card" are the same.
Thus the latter one overrides the first one.
Then we have problem when calling extcon_find_cable_index() because
edev->supported_cable[7] only matches "Dock-card".

Linus Torvalds 5d4e2d08e7 Driver core pull for 3.5-rc1
Here's the driver core, and other driver subsystems, pull request for
 the 3.5-rc1 merge window.
 
 Outside of a few minor driver core changes, we ended up with the
 following different subsystem and core changes as well, due to
 interdependancies on the driver core:
  - hyperv driver updates
  - drivers/memory being created and some drivers moved into it
  - extcon driver subsystem created out of the old Android staging switch
    driver code
  - dynamic debug updates
  - printk rework, and /dev/kmsg changes
 
 All of this has been tested in the linux-next releases for a few weeks
 with no reported problems.

Chanwoo Choi b76668ba8a Extcon: add MAX8997 extcon driver
This patch add extcon-max8997 driver to support the muic feature
of Maxim max8997 by using Extcon framework.

The extcon-max8997 driver is implemented based on 'drivers/misc/
max8997-muic.c' and then use Extcon interface instead of callback
function in struct max8997_muic_platform_data to notify cable state
of notifee which want to know always newly cable state when external
connector(e.g., USB, TA, JIG) is attached or detached.

v1
- Use Extcon interface to notify cable state of notifee instead of
 callback function when external connector is attached or detached.
- Bug fix of getting platform_data for irq_base value.
