Subject: [PATCH v2] staging: rtl8723bs: ignore unused wiphy_wowlan object warnings
Date: Thu, 16 Sep 2021 23:19:58 +0000 [thread overview]
Message-ID: <20210916231928.2021584-1-hello@bryanbrattlof.com> (raw)
The wake-on-wlan stub is unused when the device power management
functionality is disabled in the kernel, creating a warning when
building the driver.
drivers/staging/rtl8723bs/os_dep/ioctl_cfg80211.c:50:42: warning: ‘wowlan_stub’ defined but not used [-Wunused-const-variable=]
Add the __maybe_unused annotation to silence this warning.
Signed-off-by: Bryan Brattlof <hello@bryanbrattlof.com>
---
Changes from v1:
- Use the __maybe_unused annotation instead of #ifdef
