[IA64] sn: Fix zeroing of PDAs
The code uses a the following to zero out a PDA: memset(pda, 0, sizeof(pda)); But sizeof(pda) will return the size of a pointer rather than the size of the structure pointed to. This triggers the following warning from GCC: arch/ia64/sn/kernel/setup.c:582:23: warning: argument to 'sizeof' in 'memset' call is the same pointer type 'struct pda_s *' as the destination; expected 'struct pda_s' or an explicit length [-Wsizeof-pointer-memaccess] memset(pda, 0, sizeof(pda)); ^ Fix this by passing in the size of the structure using sizeof(*pda) instead.
