From 3c5f9362c4cdb1b234f4bc8cc157ee487ff5a426 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 25 Aug 2017 16:54:20 +0200 Subject: media: open.rst: remove the minor number range minor numbers use to range between 0 to 255, but that was changed a long time ago. While it still applies when CONFIG_VIDEO_FIXED_MINOR_RANGES, when the minor number is dynamically allocated, this may not be true. In any case, this is not relevant, as udev will take care of it. So, remove this useless misinformation.
