We set this using:
devs_closed |= (0x1 << bdev->minor)
Since 0x1 is an int then only the lower 32 bits are usable before we hit
a shift wrapping bug. There are some static checkers which complain
about this. I've silenced the warning by making devs_closed a 32 bit
number.
32 bits should be enough for anybody.
Not really, as bdev->minor will be in the range 0 to 47 inclusive (0 to
COMEDI_NUM_BOARD_MINORS-1). Of course, an unsigned long is insufficient
too on a 32-bit system.
