5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andrew Lunn <andrew@xxxxxxx>
commit f55d8e60f10909dbc5524e261041e1d28d7d20d8 upstream.
This function takes a pointer to a pointer, unlike sprintf() which is
passed a plain pointer. Fix up the documentation to make this clear.
Fixes: 7888fe53b706 ("ethtool: Add common function for filling out strings")
