+From 0962d9e4a57c3faa29000c63c1cb28ad39a6c80c Mon Sep 17 00:00:00 2001
+From: John Cox <jc@kynesim.co.uk>
+Date: Thu, 21 May 2020 11:49:37 +0100
+Subject: [PATCH] media: rpivid: Remove the need to have
+ num_entry_points set
+
+VAAPI H265 has num entry points but never sets it. Allow a VAAPI
+shim to work without requiring rewriting the VAAPI driver.
+num_entry_points can be calculated from the slice_segment_addr
+of the next slice so delay processing until we have that.
+
+Also includes some minor cosmetics.
+
+Signed-off-by: John Cox <jc@kynesim.co.uk>
