fbdev: omapfb: off by one in omapfb_register_client()
[ Upstream commit 5ec1ec35b2979b59d0b33381e7c9aac17e159d16 ]
The omapfb_register_client[] array has OMAPFB_PLANE_NUM elements so the
> should be >= or we are one element beyond the end of the array.
Fixes: 8b08cf2b64f5 ("OMAP: add TI OMAP framebuffer driver")
