From 73e80544954402203bc2448a2b6023377392fdab Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sat, 28 Oct 2023 21:25:11 +0200 Subject: [PATCH] net: ethtool: Fix documentation of ethtool_sprintf() 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.
