From af1ffad29ae870b4615122850f829047d43dd0a8 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 20 Aug 2008 16:44:51 -0700 Subject: V4L1: make PMS not autoprobe when builtin. From: Rene Herman 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.
