Subject: [PATCH net-next 2/9] intel: fix format warnings
From: Jesse Brandeburg <jesse.brandeburg@...el.com>
Get ahead of the game and fix all the -Wformat=2 noted warnings in the
intel drivers directory.
There are one set of i40e and iavf warnings I couldn't figure out how to
fix because the driver is already using vsnprintf without an explicit
"const char *" format string.
Tested with both gcc-12 and clang-15. I found gcc-12 runs clean after
this series but clang-15 is a little worried about the vsnprintf lines.
summary of warnings:
