Subject: [PATCH 1/2] net: dsa: microchip: Do not reinit mutexes on KSZ87xx
Date: Thu, 10 Oct 2019 20:25:07 +0200
Message-ID: <20191010182508.22833-1-marex@denx.de> (raw)

The KSZ87xx driver calls mutex_init() on mutexes already inited in
ksz_common.c ksz_switch_register(). Do not do it twice, drop the
reinitialization.
