[PATCH 1/2] extcon: Set platform drvdata in gpio_extcon_probe() and fix irq leak

[Axel Lin <axel.lin@gmail.com>]

Add missing platform_set_drvdata() in gpio_extcon_probe(), otherwise calling
platform_get_drvdata in gpio_extcon_remove() returns NULL.

Also add missing free_irq call in gpio_extcon_remove().
