Sean Anderson d6b5aac451 soc: fsl: qbman: Use raw spinlock for cgr_lock ... [ Upstream commit fbec4e7fed ] smp_call_function always runs its callback in hard IRQ context, even on PREEMPT_RT, where spinlocks can sleep. So we need to use a raw spinlock for cgr_lock to ensure we aren't waiting on a sleeping task. Although this bug has existed for a while, it was not apparent until commit ef2a8d5478 ("net: dpaa: Adjust queue depth on rate change") which invokes smp_call_function_single via qman_update_cgr_safe every time a link goes up or down.
