Subject: [PATCH] ath11k: Remove unnecessary delay in ath11k_core_suspend
Git-commit: 2dd398dee7aa5ec6b296d9915bbb1c1a76199b4a
Patch-mainline: v5.19-rc1
References: bsc#1206451
The intended delay in ath11k_core_suspend is introduced in commit
d1b0c33850d2 ("ath11k: implement suspend for QCA6390 PCI devices"),
now with ath11k_mac_wait_tx_complete added in commit ba9177fcef21
("ath11k: Add basic WoW functionalities"), that delay is not
necessary now, so remove it.
This is found in code review.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-02431-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1
