Subject: [PATCH v6 2/8] i2c: i801: Use GPIO_LOOKUP() helper macro
Date:   Tue, 24 Mar 2020 14:56:47 +0100
Message-Id: <20200324135653.6676-2-geert+renesas@glider.be>
In-Reply-To: <20200324135653.6676-1-geert+renesas@glider.be>
References: <20200324135328.5796-1-geert+renesas@glider.be>
 <20200324135653.6676-1-geert+renesas@glider.be>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

i801_add_mux() fills in the GPIO lookup table by manually populating an
array of gpiod_lookup structures.  Use the existing GPIO_LOOKUP() helper
macro instead, to relax a dependency on the gpiod_lookup structure's
member names.

While this patch is a dependency for "[PATCH v6 4/8] gpiolib: Add
support for GPIO lookup by line name", it can be applied independently.
But an Acked-by would be nice, too.
