Guangshuo Li 977f52909c arm_mpam: guard MBWU state before adding it to garbage ... __destroy_component_cfg() adds each RIS mbwu_state object to the MPAM garbage list when destroying component configuration. However, mbwu_state is allocated per RIS and only for RISes with MBWU monitors. A component can therefore have comp->cfg allocated while some RISes still have ris->mbwu_state set to NULL. Passing a NULL mbwu_state to add_to_garbage() dereferences the NULL pointer inside the macro. Skip RISes that do not have an mbwu_state object before adding them to the garbage list.
