Subject: RE: [PATCH] media: s5p-mfc fix memory leak in s5p_mfc_remove()

HI Shuah,

Which branch do you base your patches on?

I have trouble applying this path
(https://patchwork.linuxtv.org/patch/34577/) and 
"s5p-mfc fix null pointer deference in clk_core_enable()"
(https://patchwork.linuxtv.org/patch/34751/) 
onto current linuxtv/master.

The top commit of linuxtv/master is :
"commit 0db5c79989de2c68d5abb7ba891bfdb3cd3b7e05
Author: Mauro Carvalho Chehab <mchehab@...pensource.com>
Date:   Thu Jun 16 08:04:40 2016 -0300

    [media] media-devnode.h: Fix documentation"

Could you please rebase the two patches mentioned above to the
linuxtv/master?

Best wishes,
