commit: 229bd792be0bad245b78ed8f119952733a4752e5 From: David Kilroy <[email protected]> Date: Tue, 7 Dec 2010 18:50:42 +0000 Subject: [PATCH] orinoco: initialise priv->hw before assigning the interrupt
The interrupt handler takes a lock - but since commit bcad6e80f3f this lock goes through an indirection specified in the hermes_t structure. We must therefore initialise the structure before setting up the interrupt handler.
