Your suggestion about -ENOMEM is consistent with the callchain. Nothing
else is needed.
Btw:
1. kfree does not care about NULL parameter, especially in this hardly
timing sensitive path.
2. kmalloc_array for small kernel controlled arrays of integers (see
drivers/net/ethernet/freescale/gianfar.h), seriously ?
I'd suggest the janitor to introduce a dedicated struct to embed both
gfar_private.ftp_rqf{p, c}r then use a single, plain kmalloc in
gfar_ethflow_to_filer_table.
Happy tasteful 2016 :o)
