It is not required to use hard-coded offsets any more in context save and restore functions and instead use the generic offsets which have been correctly initialized during device registration. Signed-off-by: Tarun Kanti DebBarma<redacted> Signed-off-by: Charulatha V<redacted> ---

Not related to this patch but saving the status register just useless. You should rather save/restore 'wkup_set' register. Can you please fix this in relevant patch. O.w this patch looks ok to me. Regards Santosh
