[PATCH 5/5] drm: Fix return type of crc .poll()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Sparse compains:
../drivers/gpu/drm/drm_debugfs_crc.c:350:17: warning: incorrect type in initializer (different base types)
../drivers/gpu/drm/drm_debugfs_crc.c:350:17:    expected restricted __poll_t ( *poll )( ... )
../drivers/gpu/drm/drm_debugfs_crc.c:350:17:    got unsigned int ( * )( ... )

Change the .poll() return type to __poll_t to silence it.
