ARM: OMAP2+: Restore MPU power domain if cpu_cluster_pm_enter() fails
If cpu_cluster_pm_enter() fails, we need to set MPU power domain back to enabled to prevent the next WFI from potentially triggering an undesired MPU power domain state change. We already do this for omap_enter_idle_smp() but are missing it for omap_enter_idle_coupled(). Fixes: 55be2f50336f ("ARM: OMAP2+: Handle errors for cpu_pm") Signed-off-by: Tony Lindgren <tony@atomide.com>
