Subject: [PATCH v3 10/16] power: supply: axp20x_battery: use data structure instead of ID for
Date: Mon, 15 Jan 2018 11:33:44 +0100 [thread overview]
Message-ID: <c4129842e1254289ebb3ad1755879a3722bac1cf.1516012352.git-series.quentin.schulz@free-electrons.com> (raw)
In-Reply-To: <cover.2e5329bf5475a5160e613a4eb1e1377c662ce56e.1516012352.git-series.quentin.schulz-wi1+55ScJUtKEb57/3fJTNBPR1lH4CV8@public.gmane.org>
In-Reply-To: <cover.2e5329bf5475a5160e613a4eb1e1377c662ce56e.1516012352.git-series.quentin.schulz-wi1+55ScJUtKEb57/3fJTNBPR1lH4CV8@public.gmane.org>
variant specific code
We used to use IDs to select a function or a feature depending on the
variant. It's easier to maintain the code by adding data structure
storing the few differences between variants so that we don't add a pile
of if conditions.
Let's use this data structure and update the code to use it.
