RE: [PATCH] fix idiocy in asd_init_lseq_mdp()

James,

asd_write_reg_dword() is the correct implementation for writing the
LmM0INTEN_MASK to the LmSEQ_INTEN_SAVE register.

I don't honestly know.  The change was made as part of a slew of changes
by Robert Tarte at Adaptec to make the driver run on Big Endian

hope that he can enlighten us.
