Subject: [PATCH 5/5] sfc: add  missing annotation for efx_ef10_try_update_nic_stats_vf()
Date: Mon,  1 Jun 2020 19:45:52 +0100	[thread overview]
Message-ID: <20200601184552.23128-6-jbi.octave@gmail.com> (raw)
In-Reply-To: <20200601184552.23128-1-jbi.octave@gmail.com>

Sparse reports a warning at efx_ef10_try_update_nic_stats_vf()
warning: context imbalance in efx_ef10_try_update_nic_stats_vf()
	- unexpected unlock
The root cause is the missing annotation at
efx_ef10_try_update_nic_stats_vf()
Add the missing _must_hold(&efx->stats_lock) annotation
