Subject: [PATCH v6 3/4] gpiolib: Pass array info to get/set array functions
Date: Sat,  1 Sep 2018 00:56:15 +0200
Message-ID: <20180831225616.29221-4-jmkrzyszt@gmail.com> (raw)
In-Reply-To: <20180831225616.29221-1-jmkrzyszt@gmail.com>

In order to make use of array info obtained from gpiod_get_array() and
speed up processing of arrays matching single GPIO chip layout, that
information must be passed to get/set array functions.  Extend the
functions' API with that additional parameter and update all users.
Pass NULL if a user bulids an array itself from single GPIOs.
