Subject: net: dsa: microchip: Do not reinit mutexes on KSZ87xx
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=7f238ca984b9c6a89e2339c661440c775d617386;p=android-x86%2Fkernel.git

net: dsa: microchip: Do not reinit mutexes on KSZ87xx

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.
