Subject: [PATCH] media: v4l2-core/v4l2-of.c: determine bus_type only on hsync/vsync flags

From: "Lad, Prabhakar" <prabhakar.csengg@...il.com>

the bus_type needs to be determined only on the hsync/vsync flags,
this patch fixes the above by moving the check just after hsync/vsync
flags are being set.
