In fact I modified ALL le16_to_cpu() function calls to implement the
get_unaligned((u16*), to be sure !!
Instead of use get_unaligned, which surely eat cpu time, it cannot be
possible to directly align data used by the driver ? In structure and
Or maybe it exists an option in the blackfin gcc to do this automaticaly
at compilation ?
