From f841afb17476f485900bb6213cf93a64a7dc303f Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Thu, 16 Oct 2014 15:11:44 +0200 Subject: extcon: Implement OF-based extcon lookup properly Platform bus is not the only way to have extcon devices, so current implementation of of_extcon_get_extcon_dev() is broken. Also using parent device node only to get device name is quite ugly. This patch reimplements of_extcon_get_extcon_dev() to do exactly the same as extcon_get_extcon_dev() but instead of comparing names, compare node pointers.

This was introduced in 39bf369e4ed3 ("extcon: max77693: Add support dock device and buttons") while adding dock features. Assign the JIG-UART-ON back to UART path.
