Subject: [PATCH 1/2] ath10k: Move napi_enable to hif_start for consistent pairing
Date: Thu, 20 Sep 2018 10:34:25 +0530	[thread overview]
Message-ID: <20180920050426.4113-1-govinds@codeaurora.org> (raw)

There is unbalanced napi_{enable,disable}() behavior as they
are being called from hif_snoc_{power_up/stop).

The fix is to call napi_enable() from ath10k_snoc_hif_start()
so that it matches with napi_disable() being called from
ath10k_snoc_hif_stop().
