[alsa-devel] [PATCH 1/2] opti93x: fix irq releasing if the irq cannot be allocated
by Krzysztof Helt 01 Dec '09

01 Dec '09

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> Fix the bug that an irq is released if the irq's allocation fails. Move irq allocation earlier so the codec->irq is not set if the request_irq() fails.
