Subject: [PATCH 3.12 116/123] [media] v4l: vsp1: Fix VI6_WPF_SZCLIP_SIZE_MASK macro

From: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@...esas.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 03b36e4dcf422a10da8b67bce2ed00b34ec58aac upstream.

Clipping size bit of VI6_WPFn _HSZCLIP and VI6_WPFn _VSZCLIP register are from
0 bit to 11 bit. But VI6_WPF_SZCLIP_SIZE_MASK is set to 0x1FFF, this will mask
until the reserve bits. This fixes size for VI6_WPF_SZCLIP_SIZE_MASK.
