Subject: [PATCH v6 3/8] mfd: sm501: Use GPIO_LOOKUP_IDX() helper macro
Date: Tue, 24 Mar 2020 14:56:48 +0100	[thread overview]
Message-ID: <20200324135653.6676-3-geert+renesas@glider.be> (raw)
In-Reply-To: <20200324135653.6676-1-geert+renesas@glider.be>

i801_add_mux() fills in the GPIO lookup table by manually populating an
array of gpiod_lookup structures.  Use the existing GPIO_LOOKUP_IDX()
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.
