Subject: [PATCH] wifi: rtw89: fix HW scan abort not completed issue
Date: Fri, 10 May 2024 21:09:34 +0800	[thread overview]
Message-ID: <20240510130934.5825-1-pkshih@realtek.com> (raw)

From: Chih-Kang Chang <gary.chang@realtek.com>

When scan happens before suspending, rtw89_hw_scan_complete() might
happen after suspend flow. This causes the scan to be unable to
properly indicate scan completion to mac80211 before suspending. To
fix this issue, we modify to execute rtw89_hw_scan_complete() when
rtw89_hw_scan_abort() is called, regardless of result of
rtw89_hw_scan_offload().
