Re: [PATCH v1] net: alacritech: Switch to use dev_err_probe()

[Jacob Keller <jacob.e.keller@intel.com>]

nit: subject should include "net-next" for changes like this which are
cleanups meant for the net-next tree.

Nice. dev_err_probe also handles some specific behavior for
-EPROBE_DEFER, which isn't being used here. That's fine since the custom
logic only triggers specifically on -EPROBE_DEFER. It also has custom
handling to avoid logging an error message on -ENOMEM. Neat.
