intel: legacy: field get conversion
Refactor several older Intel drivers to use FIELD_GET(), which reduces lines of code and adds clarity of intent. This code was generated by the following coccinelle/spatch script and then manually repaired. @get@ constant shift,mask; type T; expression a; @@ ( -((T)((a) & mask) >> shift) +FIELD_GET(mask, a) and applied via: spatch --sp-file field_prep.cocci --in-place --dir \ drivers/net/ethernet/intel/ Cc: Julia Lawall <Julia.Lawall@inria.fr> CC: Alexander Lobakin <aleksander.lobakin@intel.com> Reviewed-by: Marcin Szycik <marcin.szycik@linux.intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Pucha Himasekhar Reddy <himasekharx.reddy.pucha@intel.com> (A Contingent worker at Intel) Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
