drm/i915: Silence compiler warning for hsw_power_well_enable()
Not all compilers are able to determine that pg is guarded by wait_fuses and so may think that pg is used uninitialized. Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Fixes: b2891eb2531e ("drm/i915/hsw+: Add has_fuses power well attribute") Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Imre Deak <imre.deak@intel.com> Cc: Arkadiusz Hiler <arkadiusz.hiler@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20171002100416.25865-1-chris@chris-wilson.co.uk Reviewed-by: Imre Deak <imre.deak@intel.com> (cherry picked from commit 320671f94ada80ff036cc9d5dcd730ba4f3e0f1a) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
