For aesthetics, rename the 'boardinfo' variables to 'board'. That name
is more commonly used for the boardinfo pointer in comedi drivers.

this is more than just rename.

but won't it be better if the code just looked like:
if (context < ARRAY_SIZE(vmk80xx_boardinfo))
	board = &vmk80xx_boardinfo[context];
else
	return -ENODEV;

Also, the additional sanity check ought to be in a different patch.
