From b54ff9398ac7d38a129167b580383943592b6f08 Mon Sep 17 00:00:00 2001 From: Rene Herman Date: Wed, 3 Sep 2008 16:48:21 -0300 Subject: [PATCH] V4L/DVB (8727): 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 behaviour moreover.
