[ Upstream commit b6f23d3817b965bcd6d72aab1f438ff6d16a0691 ] The for loop in i40e_set_vsi_promisc() reports errors via dev_err() but does not propagate the error up the call chain. Instead it continues the loop and potentially overwrites the reported error value. This results in the error being recorded in the log buffer, but the caller might never know anything went the wrong way. To avoid this situation i40e_set_vsi_promisc() needs to temporarily store the error after reporting it. This is still not optimal as multiple different errors may occur, so store the first error and hope that's the main issue.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
