Subject[PATCH 1/2] cpuidle: psci: Fix regression leading to no genpd governor
Date
While factoring out the PM domain related code from PSCI domain driver into
a set of library functions, a regression when initializing the genpds got
introduced. More precisely, we fail to assign a genpd governor, so let's
fix this.

Fixes: 9d976d6721df ("cpuidle: Factor-out power domain related code from PSCI domain driver")
