[PATCH] net/qed: allow old cards not supporting "num_images" to work
From: Louis Leseur
Date: Thu Nov 21 2024 - 12:30:12 EST
Commit 43645ce03e0063d7c4a5001215ca815188778881 added support for
populating flash image attributes, notably "num_images". However, some
cards were not able to return this information. In such cases, the
driver would return EINVAL, causing the driver to exit.
We added a check to return EOPNOTSUPP when the card is not able to
return these information, allowing the driver continue instead of
returning an error.
