Message-ID: <ZDqKb1iuoSQTYXJM@kernelhacking.kernelhacking.example.com>
Date: Sat, 15 Apr 2023 13:28:47 +0200
From: Luke Koch <lu.ale.koch@...il.com>
To: gregkh@...uxfoundation.org
Cc: linux-staging@...ts.linux.dev, linux-kernel@...r.kernel.org
Subject: [PATCH] staging: wlan-ng: replace rate macros
Change p80211msg_dot11req_scan_results rate members to struct arrays
instead of individually numbered member structs.
Replace macros to set rates with loops to avoid checkpatch warning
and adhere to linux coding style.
Reported by checkpatch:
CHECK: Macro argument reuse 'N' - possible side-effects?
