From b5cff595bd005dba8051e9125f0ed28b5ff05c89 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 23 Dec 2012 13:14:20 -0200 Subject: [PATCH] [media] em28xx: prefer_bulk parameter is read-only As the bulk mode is set at device's probe, it is not possible to change it later. So, change the parameter to be read only after modprobing.
