Subject: [PATCH 4.4 20/93] fbdev: aty: SPARC64 requires FB_ATY_CT

From: Randy Dunlap <rdunlap@...radead.org>

[ Upstream commit c6c90c70db4d9a0989111d6b994d545659410f7a ]

It looks like SPARC64 requires FB_ATY_CT to build without errors,
so have FB_ATY select FB_ATY_CT if both SPARC64 and PCI are enabled
instead of using "default y if SPARC64 && PCI", which is not strong
enough to prevent build errors.

As it currently is, FB_ATY_CT can be disabled, resulting in build
errors:

ERROR: modpost: "aty_postdividers" [drivers/video/fbdev/aty/atyfb.ko] undefined!
ERROR: modpost: "aty_ld_pll_ct" [drivers/video/fbdev/aty/atyfb.ko] undefined!
