Subject[PATCH v4 3/7] media: i2c: imx335: Improve configuration error reporting
Date
From: Kieran Bingham <kieran.bingham@ideasonboard.com>

The existing imx335_parse_hw_config function has two paths
that can be taken without reporting to the user the reason
for failing to accept the hardware configuration.

Extend the error reporting paths to identify failures when
probing the device.
