Chanwoo writes:

Update extcon next for v6.8

Detailed description for this pull request:
1. Fix possible memory leak of device name in extcon_dev_register()
 : Fix memory leak on error path of extcon_dev_register().

2. Set interrupt polarity based on device-tree for extcon-usbc-tusb320.c
 :Remove 'IRQF_TRIGGER_FALLING' request which is not allowed on
 every interrupt controller (i.e. arm64 GIC). Replace flag by a
 request that depends on the actual device-tree setting.

3. Fix the comment style according to guide on extcon-qcom-spmi-misc.c.
