gcc complains that:
drivers/gpu/drm/i915/i915_debugfs.c: In function ‘display_crc_ctl_write’:
drivers/gpu/drm/i915/i915_debugfs.c:2393:2: warning: ‘val’ may be used uninitialized in this function [-Wuninitialized]
drivers/gpu/drm/i915/i915_debugfs.c:2350:6: note: ‘val’ was declared here
but it can't see that we're going to use val only in the success case.
So shut it up.
