[PATCH 5.10 317/593] drm/rockchip: lvds: Fix an error handling path

From: Greg Kroah-Hartman
Date: Mon Jul 12 2021 - 02:57:47 EST


From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 3dfa159f6b0c054eb63673fbf643a5f2cc862e63 ]

'ret' is know to be 0 a this point. Checking the return value of
'phy_init()' and 'phy_set_mode()' was intended instead.

So add the missing assignments.
