Subject[PATCH AUTOSEL 4.9 14/91] media: i2c: ov2659: Fix missing 720p register config
Date
From: Benoit Parrot <bparrot@ti.com>

[ Upstream commit 9d669fbfca20e6035ead814e55d9ef1a6b500540 ]

The initial registers sequence is only loaded at probe
time. Afterward only the resolution and format specific
register are modified. Care must be taken to make sure
registers modified by one resolution setting are reverted
back when another resolution is programmed.

This was not done properly for the 720p case.
