From 99486b8e6140da7721c932e708a6c17dc1dd970a Mon Sep 17 00:00:00 2001 From: Josh Triplett Date: Tue, 13 Aug 2013 16:23:17 -0700 Subject: [PATCH] i915: Add a Kconfig option to turn on i915.preliminary_hw_support by default When building kernels for a preliminary hardware target, having to add a kernel command-line option can prove inconvenient. Add a Kconfig option that changes the default of this option to 1.
