[PATCH AUTOSEL 4.14 06/27] net: dsa: microchip: initialize mutex before use

[Sasha Levin <sashal@kernel.org>]

From: Tristram Ha <Tristram.Ha@microchip.com>

[ Upstream commit 284fb78ed7572117846f8e1d1d8e3dbfd16880c2 ]

Initialize mutex before use.  Avoid kernel complaint when
CONFIG_DEBUG_LOCK_ALLOC is enabled.

Fixes: b987e98e50ab90e5 ("dsa: add DSA switch driver for Microchip KSZ9477")
