From 03019759b98de92b5507c8c2f6e253a35d59c868 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Tue, 2 Oct 2012 09:14:59 +0900 Subject: [PATCH] extcon: adc-jack: Fix checking return value of request_any_context_irq On failure, request_any_context_irq() returns a negative value. On success, it returns either IRQC_IS_HARDIRQ or IRQC_IS_NESTED. Also ensure adc_jack_probe() return 0 on success.
