drm/i915: intel_display.c handle latency variable efficiently
By handling latency variable efficiently we also get rid of this warning : CC [M] drivers/gpu/drm/i915/intel_display.o drivers/gpu/drm/i915/intel_display.c: In function ‘igd_enable_cxsr’: drivers/gpu/drm/i915/intel_display.c:1918: warning: ‘latency’ may be used uninitialized in this function Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
