Subject: [PATCH 4.19 11/30] net: phy: DP83822: clear MISR2 register to disable interrupts

From: Clément Léger <clement.leger@...tlin.com>

[ Upstream commit 37c9d66c95564c85a001d8a035354f0220a1e1c3 ]

MISR1 was cleared twice but the original author intention was probably
to clear MISR1 & MISR2 to completely disable interrupts. Fix it to
clear MISR2.
