This can be simplified as
if (channel < 7)
*val = !!(data->alarm & BIT(channel));
else

I don't immediately see the problem with the current code, nor do I see a functional
difference. Please explain. Either case, the switch statement is unnecessary.

As with the other patches, this is not an acceptable patch description.
On top of that, it introduces a non-standard attribute without documenting
it nor providing a rationale explaining the need for it. Also, this is not
an alarm. The bit says "everything is normal". I fail to see the value of
such an attribute, much less as an "alarm" attribute.
