Subject: [PATCH 4.19 37/86] net: ethernet: ave: Fix error returns in ave_init

From: Wang Hai <wanghai38@...wei.com>

[ Upstream commit 1264d7fa3a64d8bea7aebb77253f917947ffda25 ]

When regmap_update_bits failed in ave_init(), calls of the functions
reset_control_assert() and clk_disable_unprepare() were missed.
Add goto out_reset_assert to do this.

Fixes: 57878f2f4697 ("net: ethernet: ave: add support for phy-mode setting of system controller")
