Subject: [PATCH 2/4] PM / Domains: Drop unused in-parameter to some genpd functions
Date: Thu, 25 Apr 2019 11:04:11 +0200	[thread overview]
Message-ID: <20190425090413.10700-3-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20190425090413.10700-1-ulf.hansson@linaro.org>

Both genpd_alloc_dev_data() and genpd_add_device(), whom are internal genpd
functions, allows a struct gpd_timing_data *td to be passed as an
in-parameter. However, as NULL is always passed, let's just drop the
in-parameter altogether.
