Subject: Patch(?): linux-2.4.0-test11-pre5 ISAPNP_DEVICE simplification
Date: Thu, 16 Nov 2000 02:24:51 -0800 [thread overview]
Message-ID: <200011161024.CAA01591@adam.yggdrasil.com> (raw)
I think the definition of ISAPNP_DEVICE in
linux-2.4.0-test11-pre5/include/linux/isapnp.h is unnecessarily complex.
Here is a proposed patch.
