From: Luke Koch <lu.ale.koch@...il.com>
To: gregkh@...uxfoundation.org
Cc: error27@...il.com, linux-staging@...ts.linux.dev,
linux-kernel@...r.kernel.org
Subject: [PATCH v4] 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?
Signed-off-by: Luke Koch <lu.ale.koch@...il.com>
---
v2: - Fix array underflow and conditions with respect to the start at 0
v3: - Remove unnecessary spaces
v4: - Fix patch formatting
