Crypto: chelsio - Fixes a hang issue during driver registration
This issue occurs only when multiadapters are present. Hang happens because assign_chcr_device returns u_ctx pointer of adapter which is not yet initialized as for this adapter cxgb_up is not been called yet. The last_dev pointer is used to determine u_ctx pointer and it is initialized two times in chcr_uld_add in chcr_dev_add respectively. The fix here is don't initialize the last_dev pointer during chcr_uld_add. Only assign to value to it when the adapter's initialization is completed i.e in chcr_dev_add. Fixes: fef4912b66d62 ("crypto: chelsio - Handle PCI shutdown event"). Signed-off-by: Ayush Sawal <ayush.sawal@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
