SCSI: Fix incorrect memset in bnx2fc_parse_fcp_rsp
commit 16da05b1158d1bcb31656e636a8736a663b1cf1f upstream.
gcc 4.8 warns because the memset only clears sizeof(char *) bytes, not
the whole buffer. Use the correct buffer size and clear the whole sense
buffer.
/backup/lsrc/git/linux-lto-2.6/drivers/scsi/bnx2fc/bnx2fc_io.c: In
function 'bnx2fc_parse_fcp_rsp':
/backup/lsrc/git/linux-lto-2.6/drivers/scsi/bnx2fc/bnx2fc_io.c:1810:41:
warning: argument to 'sizeof' in 'memset' call is the same expression as
the destination; did you mean to provide an explicit length?
[-Wsizeof-pointer-memaccess]
memset(sc_cmd->sense_buffer, 0, sizeof(sc_cmd->sense_buffer));
