Subject: [PATCH -next v2] net: ethernet: Simplify bool conversion

The result of 'scaled_ppm < 0' is Boolean, and the question mark
expression is redundant, remove it to clear the below warning:

./drivers/net/ethernet/renesas/rcar_gen4_ptp.c:32:40-45: WARNING: conversion to bool not needed here

The Subject line is too generic. It is a good idea to run git log on
the file you are changing and see how it is generally referred to:

b48b89f9c189 net: drop the weight argument from netif_napi_add

e7d966f9ea52 sh_eth: sh_eth_close() always returns 0
be94a51f3e5e ravb: ravb_close() always returns 0

Without something specific like ravb, you won't get the right people
noticing the patch.
