From e2572686a5a8fa35f8d1a449311f1b98165e4015 Mon Sep 17 00:00:00 2001 From: Philipp Hortmann Date: Mon, 18 Sep 2023 18:43:10 +0200 Subject: [PATCH] staging: rtl8192e: Fix compiler warning truncated writing of iwe.u.name iwe.u.name and proto_name have both 16 bytes of space. But when writing to iwe.u.name the first 10 bytes are used by the fixed string "IEEE802.11". Evaluating the code shows that only the following strings can occur in proto_name: "N-24G", "g", "b", "bg". Therefore it is sufficient to shorten proto_name to 6 bytes.
