Subject: [PATCH V5 mlx5-next 07/13] vfio: Add a macro for VFIO_DEVICE_STATE_ERROR
Date: Wed, 27 Oct 2021 12:56:52 +0300	[thread overview]
Message-ID: <20211027095658.144468-8-yishaih@nvidia.com> (raw)
In-Reply-To: <20211027095658.144468-1-yishaih@nvidia.com>

Add a macro for VFIO_DEVICE_STATE_ERROR to be used to set/check an error
state.

In addition, update existing macros that include _SAVING | _RESUMING to
use it.
