History
Sean Anderson fbec4e7fed soc: fsl: qbman: Use raw spinlock for cgr_lock 
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.

Fixes: 96f413f476 ("soc/fsl/qbman: fix issue in qman_delete_cgr_safe()")
