In suspend() host sleep is activated using already configured host sleep parameters through wol command, and in resume() host sleep is cancelled. Earlier priv->fw_ready flag used to reset and set in suspend and resume handler respectively. Since after suspend only host goes into sleep state and firmware is always ready, those changes in flag state are removed. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: John W.
