* [PATCH, net] ibmvnic: fix firmware version when no firmware level has been provided by the VIOS server

Older versions of VIOS servers do not send the firmware level in the VPD
buffer for the ibmvnic driver. Thus, not only the current message is mis-
leading but the firmware version in the ethtool will be NULL. Therefore,
this patch fixes the firmware string and its warning.

Fixes: 4e6759be28e4 ("ibmvnic: Feature implementation of VPD for the ibmvnic driver")

Applied.

Please do not put empty lines between Fixes: and Signed-off-by: and other
tags, all tags are equal and are placed together in an uninterrupted
sequences of consequetive lines.

Thank you.

Is "N/A" the right thing to report? Would something like "Unknown" or "Unreported" be better?

The sentence structure here seems awkward. I would probably just get rid of this error and this one later in the function.

	dev_err(dev, "Failed to isolate FW level string\n");

Instead just check and report if adapter->fw_version == NULL in the complete: label section.

Hello Tyrel,

I concur with your observations, but since this patch has already been 
merged, I'll address them in another patch.

Thank you for your review,

Fair enough. I didn't realize David had already merged it till after I sent my review.
