[PATCH net-next 0/4] sfc: clean up some W=1 build warnings

[Edward Cree <ecree@solarflare.com>]

A collection of minor fixes to issues flagged up by W=1.
After this series, the only remaining warnings in the sfc driver are
 some 'member missing in kerneldoc' warnings from ptp.c.
Tested by building on x86_64 and running 'ethtool -p' on an EF10 NIC;
 there was no error, but I couldn't observe the actual LED as I'm
 working remotely.

[ Incidentally, ethtool_phys_id()'s behaviour on an error return
  looks strange — if I'm reading it right, it will break out of the
  inner loop but not the outer one, and eventually return the rc
  from the last run of the inner loop.  Is this intended? ]

Edward Cree (4):
  sfc: fix W=1 warnings in efx_farch_handle_rx_not_ok
  sfc: fix unused-but-set-variable warning in
    efx_farch_filter_remove_safe
  sfc: fix kernel-doc on struct efx_loopback_state
  sfc: return errors from efx_mcdi_set_id_led, and de-indirect
