Subject: [PATCH v5] staging: octeon-ethernet: support of_get_mac_address new ERR_PTR error
Date: Fri, 3 May 2019 17:32:47 +0200 [thread overview]
Message-ID: <1556897567-22247-1-git-send-email-ynezz@true.cz> (raw)
In-Reply-To: <1556893635-18549-9-git-send-email-ynezz@true.cz>
There was NVMEM support added to of_get_mac_address, so it could now return
ERR_PTR encoded error values, so we need to adjust all current users of
of_get_mac_address to this new fact.
Signed-off-by: Petr Štetiar <ynezz@true.cz>

Changes since v3:
* IS_ERR_OR_NULL -> IS_ERR
Changes since v4:
* I've just blindly replaced IS_ERR_OR_NULL with IS_ERR in v4, but this was
wrong, as I've just realized, that we still need to check for NULL in this
particular case as well, so I've added back IS_ERR_OR_NULL check
