6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@xxxxxxx>
[ Upstream commit 80da96d735094ea22985ced98bc57fe3a4422921 ]
The recent rewrite with the use of regular atomic helpers broke the
DPMS unblanking on X11. Fix it by moving the call of
bochs_hw_blank(false) from CRTC mode_set_nofb() to atomic_enable().
Fixes: 2037174993c8 ("drm/bochs: Use regular atomic helpers")
