[PATCH v5] media: mt9p031/mt9t001/mt9v032: use V4L2_CID_TEST_PATTERN for test pattern control
From: Prabhakar
Date: Wed Oct 03 2012 - 09:53:59 EST
From: Lad, Prabhakar <prabhakar.lad@xxxxxx>
V4L2_CID_TEST_PATTERN is now a standard control.
This patch replaces the user defined control for test
pattern to make use of standard control V4L2_CID_TEST_PATTERN.

Changes for v5:
1: Fixed the min value of mt9v032_test_pattern_color control
to zero which wrongly set to 4, pointed out by Laurent.
Changes for v4:
1: Fixed some grammatical issues, pointed by Laurent.
Changes for v3:
1: Used cluster in mt9v032 for test pattern,
pointed by Laurent.
Changes for v2:
1: Fixed review comments pointed by Laurent.
