From b945f3fa829a7315488f4d39a866dfbb29e8a49a Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Sat, 16 Jun 2012 11:55:18 +0800 Subject: extcon: Set platform drvdata in gpio_extcon_probe() and fix irq leak 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().
