stable inclusion from linux-4.19.207 commit 283b8b67b3df74ca9df45431388ca422d14b6253
--------------------------------
[ Upstream commit 5147f0906d50a9d26f2b8698cd06b5680e9867ff ]
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.
