[PATCH v2 net] net: phy: marvell: Fix invalid comparison in the resume and suspend functions.

[Kurt Cancemi]

This bug resulted in only the current mode being resumed and suspended when
the PHY supported both fiber and copper modes and when the PHY only supported
copper mode the fiber mode would incorrectly be attempted to be resumed and
suspended.

Fixes: 3758be3dc162 ("Marvell phy: add functions to suspend and resume both interfaces: fiber and copper links.")

Nitpick: We don't use dots to end subject lines.

However, the commit in question has, and the Fixes: quoted summary line
needs to exactly match the summary line from the commit in question. So,
the fixes line is unfortunately correct in this instance.

Hi Kurt

Best practice is to add any Reviewed-by or Tested-by to the patch
whenever you repost it, except when you make major changes. Otherwise
they can get lost.

You should align the continuation lines so that the start matches 
the opening parenthesis. I'll fix it up when applying for you this 
time but please make sure to run checkpatch.pl --strict on patches
before submission. Thanks!
