Subject: [PATCH v2 04/11] media: imx: utils: Handle Bayer format lookup through a selection flag
Date: Fri, 27 Mar 2020 00:08:33 +0200
Message-ID: <20200326220840.18540-5-laurent.pinchart@ideasonboard.com> (raw)
In-Reply-To: <20200326220840.18540-1-laurent.pinchart@ideasonboard.com>

The format lookup (and enumeration) functions take a boolean flag to
tell if Bayer formats should be considered. This leads to hard to read
lines such as

	return enum_format(fourcc, NULL, index, cs_sel, true, false);

where the boolean parameters can easily be mixed. To make the code
clearer, add a CS_SEL_BAYER flag that can be passed through the
codespace_sel parameter of the lookup functions to replace the bool
parameter.
