From: Bjorn Helgaas Date: Fri, 27 Jun 2008 22:57:05 +0000 (-0600) Subject: PNP: introduce pnp_irq_mask_t typedef X-Git-Tag: v2.6.27-rc1~1050^2~17 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7aefff51854ccd33599c40b4e360d94cb2b7622f;p=linux-2.6 PNP: introduce pnp_irq_mask_t typedef 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().
