[RESEND PATCH 5.10.y-cip 30/40] clk: renesas: rzg2l: propagate return value of_genpd_add_provider_simple()

Lad Prabhakar

commit 33748744f15a110a233b6ae0380f476006e770f0 upstream.

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().
