Subject: [PATCH net v3] net: ti: icssg-prueth: Add missing icss_iep_put to
error path
From: Jan Kiszka <jan.kiszka@...mens.com>
Analogously to prueth_remove, just also taking care for NULL'ing the
iep pointers.
Fixes: 186734c15886 ("net: ti: icssg-prueth: add packet timestamping and ptp support")
Fixes: 443a2367ba3c ("net: ti: icssg-prueth: am65x SR2.0 add 10M full duplex support")
Signed-off-by: Jan Kiszka <jan.kiszka@...mens.com>

Changes in v3:
- consolidate cleanup logic further [Wojciech]
- make sure to NULL iep pointers
Changes in v2:
- add proper tags
This was lost from the TI SDK version while ripping out SR1.0 support - which we are currently restoring for upstream.
