Subject: [PATCH] enetc: fix build warning
Date: Thu, 3 Dec 2020 23:37:21 +0100 [thread overview]
Message-ID: <20201203223747.1337389-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
When CONFIG_OF is disabled, there is a harmless warning about
an unused variable:
enetc_pf.c: In function 'enetc_phylink_create':
enetc_pf.c:981:17: error: unused variable 'dev' [-Werror=unused-variable]
Slightly rearrange the code to pass around the of_node as a
function argument, which avoids the problem without hurting
readability.
Fixes: 71b77a7a27a3 ("enetc: Migrate to PHYLINK and PCS_LYNX")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
