[PATCH AUTOSEL 5.8 17/24] net: usb: pegasus: Proper error handing when setting pegasus' MAC address

[Sasha Levin]

From: Petko Manolov <petko.manolov@konsulko.com>

[ Upstream commit f30e25a9d1b25ac8d40071c4dc2679ad0fcdc55a ]

v2:

If reading the MAC address from eeprom fail don't throw an error, use randomly
generated MAC instead.  Either way the adapter will soldier on and the return
type of set_ethernet_addr() can be reverted to void.

v1:

Fix a bug in set_ethernet_addr() which does not take into account possible
errors (or partial reads) returned by its helpers.  This can potentially lead to
writing random data into device's MAC address registers.

[PATCH AUTOSEL 5.8 18/24] net: usb: rtl8150: set random MAC address when set_ethernet_addr() fails

[Sasha Levin]

From: Anant Thazhemadam <anant.thazhemadam@gmail.com>

[ Upstream commit f45a4248ea4cc13ed50618ff066849f9587226b2 ]

When get_registers() fails in set_ethernet_addr(),the uninitialized
value of node_id gets copied over as the address.
So, check the return value of get_registers().

If get_registers() executed successfully (i.e., it returns
sizeof(node_id)), copy over the MAC address using ether_addr_copy()
(instead of using memcpy()).

Else, if get_registers() failed instead, a randomly generated MAC
address is set as the MAC address instead.

This autosel is premature.

This patch always sets a random MAC.
See the follow on patch: https://lkml.org/lkml/2020/10/11/131
To my knowledge, this follow-ob has yet to be applied:

So this needs to use
	if (!ret) {

or 
	if (ret < 0)

and reversed code blocks
