serial: 8250: omap: Flush PM QOS work on remove
[ Upstream commit d0b68629bd2fb61e0171a62f2e8da3db322f5cf6 ]
Rebinding 8250_omap in a loop will at some point produce a warning for
kernel/power/qos.c:296 cpu_latency_qos_update_request() with error
"cpu_latency_qos_update_request called for unknown object". Let's flush
the possibly pending PM QOS work scheduled from omap8250_runtime_suspend()
before we disable runtime PM.
Fixes: 61929cf0169d ("tty: serial: Add 8250-core based omap driver")
