Subject: [PATCH] net: macb: undo operations in case of failure
Date: Wed, 17 Jun 2020 16:23:55 +0300	[thread overview]
Message-ID: <1592400235-11833-1-git-send-email-claudiu.beznea@microchip.com> (raw)

Undo previously done operation in case macb_phylink_connect()
fails. Since macb_reset_hw() is the 1st undo operation the
napi_exit label was renamed to reset_hw.

Fixes: b2b041417299 ("net: macb: convert to phylink")
