[PATCH 11/15] OMAP: GPIO: Remove hardcoded offsets in ctxt save/restore

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
