[Openchrome-devel] [PATCH] fix wrong arch_phys_wc_add instead of arch_phys_wc_del

[Thomas Schlichter]

Dear James,

the commit http://cgit.freedesktop.org/openchrome/drm-openchrome/commit/?id=ba0b86854415501031f21548e0f66a1f8dd82e7b accidentally 
changed a mtrr_del() to arch_phys_wc_add() instead of a arch_phys_wc_del(). 
The patch below should hopefully fix this.

Kind regards,
  Thomas
