Subject: [PATCH 2/4] clk: renesas: rzg2l: propagate return value of_genpd_add_provider_simple()
Date:   Wed, 17 Nov 2021 11:50:59 +0000
Message-Id: <20211117115101.28281-3-prabhakar.mahadev-lad.rj@bp.renesas.com>
In-Reply-To: <20211117115101.28281-1-prabhakar.mahadev-lad.rj@bp.renesas.com>

Precedence: bulk

of_genpd_add_provider_simple() might fail, this patch makes sure we check
the return value of of_genpd_add_provider_simple() by propagating the
return value to the caller of rzg2l_cpg_add_clk_domain().
