[patch] staging: comedi: comedi_bond: silence a shift wrapping warning

[Dan Carpenter]

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.
