Subject: [PATCH] ath10k: Fix NAPI enable/disable symmetry for AHB interface
Date: Mon, 20 Mar 2017 20:52:46 +0530	[thread overview]
Message-ID: <1490023366-8176-1-git-send-email-mohammed@qca.qualcomm.com> (raw)

From: Mohammed Shafi Shajakhan <mohammed@qti.qualcomm.com>

Move NAPI enable to 'ath10k_ahb_hif_start' from
'ath10k_ahb_hif_power_up'. This is to maintain the symmetry
of calling napi_enable() from ath10k_ahb_hif_start() so that it
matches with  napi_disable() being called from ath10k_pci_hif_stop().

This change is based on the crash fix from Kalle for PCI interface in
commit 1427228d5869 ("ath10k: fix napi crash during rmmod when probe
firmware fails").
