Reg. #308263 - Collinstown Industrial Park, Leixlip, County Kildare - Ireland Precedence: bulk List-ID: X-Mailing-List: linux-crypto@vger.kernel.org The function adf_dev_init() ignores the error code reported by enable_vf2pf_comms(). If the latter fails, e.g. the VF is not compatible with the pf, then the load of the VF driver progresses. This patch changes adf_dev_init() so that the error code from enable_vf2pf_comms() is returned to the caller.
