From 8b7fc4214b550fafe595330e28d7c2c72b8b62f6 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Wed, 14 Sep 2005 14:19:17 -0700 Subject: [PATCH] add PCI IDs so RME32 and RME96 drivers build While doing an allyesconfig build, I noticed that the commit commit 8cdfd2519c6c9a1e6057dc5970b2542b35895738 Author: Takashi Iwai Date: Wed Sep 7 14:08:11 2005 +0200 [ALSA] Remove superfluous PCI ID definitions broke the RME32 and RME96 drivers, since the PCI IDs they use seem to have changed names. Here's a patch to fix this -- compile tested only, since I have no idea what the hardware even is. Fix the build of the RME32 and RME96 drivers by having them use the PCI_DEVICE_ID_RME_xxx names defined in instead of the PCI_DEVICE_ID_xxx names that they used to define themselves. Also fix the typo in the id PCI_DEVICE_IDRME__DIGI96_8_PAD_OR_PST so the name is PCI_DEVICE_ID_RME_DIGI96_8_PAD_OR_PST.
