>From 87f37f786d4c73275feaa36ea51f9272f0b0a709 Mon Sep 17 00:00:00 2001 From: Rene Herman Date: Sat, 9 Aug 2008 20:39:19 +0200 Subject: [PATCH] V4L1: make PMS not autoprobe when builtin. The old Mediavision Pro Movie Studio legacy ISA V4L1 driver was found to hang the boot during Ingo Molnar's testing of randconfig kernels. Have it require a "pms.enable=1" kernel parameter to enable the driver when builtin which avoids such problems. This is a deprecated and, very likely, unused driver. Nothing changes modular moreover.
