Subject: [patch 05/15] PNP: introduce pnp_irq_mask_t typedef
Date: Fri, 30 May 2008 16:48:58 -0600 [thread overview]
Message-ID: <20080530224932.360968516@ldl.fc.hp.com> (raw)
In-Reply-To: 20080530224853.976744229@ldl.fc.hp.com
[-- Attachment #1: pnp-irq-bitmap-decl --]
[-- Type: text/plain, Size: 6198 bytes --]
This adds a typedef for the IRQ bitmap, which should cause
no functional change, but will make it easier to pass a
pointer to a bitmap to pnp_register_irq_resource().
