Subject: [PATCH net-next 11/17] net: sfp: allow fault processing to transition to other states
Date: Sun, 10 Nov 2019 14:07:04 +0000 [thread overview]
Message-ID: <E1iTnrs-0005BD-LE@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20191110140530.GA25745@shell.armlinux.org.uk>
Add the next state to sfp_sm_fault() so that it can branch to other
states. This will be necessary to improve the initialisation path.
Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
