Subject: PM / Domains: Fix pm_genpd_poweron()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fe202fde50a986a8510c62a76dc8733c1a8fac86;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

PM / Domains: Fix pm_genpd_poweron()

The local variable ret is defined twice in pm_genpd_poweron(), which
causes this function to always return 0, even if the PM domain's
.power_on() callback fails, in which case an error code should be
returned.

Remove the wrong second definition of ret and additionally remove an
unnecessary definition of wait from pm_genpd_poweron().
