Subject: [PATCH net-next 07/11] net: phy: marvell: use positive logic for link state
Date: Tue, 17 Dec 2019 13:39:31 +0000	[thread overview]
Message-ID: <E1ihD4V-0001z2-O5@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20191217133827.GQ25745@shell.armlinux.org.uk>

Rather than using negative logic:

	if (there is no link)
		set link = 0
	else
		set link = 1

use the more natural positive logic:

	if (there is link)
		set link = 1
	else
		set link = 0
