Enabling format checking in dprintk() shows that wd7000_biosparam
uses an incorrect format string for sector_t:
drivers/scsi/wd7000.c: In function 'wd7000_biosparam':
drivers/scsi/wd7000.c:1594:21: error: format '%d' expects argument of type
'int', but argument 3 has type 'sector_t {aka long long unsigned int}'
[-Werror=format=]
As sector_t can be 32-bit wide, this adds a cast to 'u64' and prints
that with the correct format. The change to use no_printk()
generally helps with finding this kind of hidden format string bug,
and I found that when building with "-Wextra", which warned about
an empty else clause in
} else
dprintk("ok!\n");
