5.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Kees Cook <keescook@xxxxxxxxxxxx> [ Upstream commit 69831173fcbbfebb7aa2d76523deaf0b87b8eddd ] Clean up some style issues: - Use ARRAY_SIZE() even though it's a u8 array. - Remove redundant CHANNEL_MAX_NUMBER_2G define. Additionally fix some dead code WARNs.
