Subject: devm_* vs. PROBE_DEFFER: memory leaks?

Hi!

Is devm_ supposed to work with EPROBE_DEFFER?

Probe function is now called multiple times; is memory freed between
calling probe()? Will allocations from failed probe()s remain after
the driver is inserted successfully, leaking memory?

Thanks,
									Pavel
