This is not really necessary, as part -of power management all the data structures are intact, all the -previously allocated resources can be used after coming out of low -power. - -This patch uses the suspend and resume callbacks for freeze and -restore which initializes the hardware correctly without unregistering -or releasing the resources, this should also help in reducing the time -to restore. - -Also this patch fixes a bug in stmmac_pltfr_restore and -stmmac_pltfr_freeze where it tries to get hold of platform data via -dev_get_platdata call, which would return NULL in device tree cases and -the next if statement would crash as there is no NULL check. - -Signed-off-by: Srinivas Kandagatla -Acked-by: Giuseppe Cavallaro -Signed-off-by: David S.
