net: phy: marvell: clear wol event before setting it
[ Upstream commit b6a930fa ] If WOL event happened once, the LED[2] interrupt pin will not be cleared unless we read the CSISR register. If interrupts are in use, the normal interrupt handling will clear the WOL event. Let's clear the WOL event before enabling it if !phy_interrupt_is_valid().
