From 16c7bcadff2222b297d13951dc30e133f56d0154 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 20 Nov 2008 08:56:19 -0300 Subject: [PATCH] V4L/DVB (9652): em28xx: merge AC97 vendor id's into a single var This makes easier to identify vendor ID, since AC97 vendors are generally identified by 3 bytes. The remaining byte is used by the vendor to identify its devices.
