vt: Don't check KD_GRAPHICS when binding/unbinding
This was introduced in commit 6db4063c5b72b46e9793b0f141a7a3984ac6facf Author: Antonino A. Daplas <adaplas@gmail.com> Date: Mon Jun 26 00:27:12 2006 -0700 [PATCH] VT binding: Add sysfs control to the VT layer with the justification "In addition, if any of the consoles are in KD_GRAPHICS mode, binding and unbinding will not succeed. KD_GRAPHICS mode usually indicates that the underlying console hardware is used for other purposes other than displaying text (ie X). This feature should prevent binding/unbinding from interfering with a graphics application using the VT." I think we should lift this artificial restriction though: - KD_GRAPHICS doesn't get cleaned up automatically, which means it's easy to have terminals stuck in KD_GRAPHICS when hacking around on X. - X doesn't really care, especially with drm where kms already blocks fbdev (and hence fbcon) when there's an active compositor. - This is a root-only interface with a separate .config option and it's possible to hang your machine already anyway if you unload/reload drivers and don't know what you're doing. With this patch i915.ko module reloading works again reliably, something in the recent fedora upgrades broke things. Cc: Antonino A.
