The code for parsing layers in devargs could reference past
the end of layers[] array on stack.

The array of debug status strings did not match possible enum
values. Add the missing element and a static assert to make sure
the table has all possible values.

For more complete description see.

Calling memcmp on same structure will always be true.
Replace with same conditional used elsewhere.

The type mask is 64 bit value, doing a shift of literal 1 (32 bit)
will result in int type (32 bit) and cause truncation.

The dqrr_held mask is 64 bit but updates were getting truncated
because 1 is of type int (32 bit) and the result shift of int is of
type int (32 bit); therefore any value >= 32 would get truncated.

The dqrr_held mask is 64 bit but updates were getting truncated
because 1 is of type int (32 bit) and the result shift of int is of
type int (32 bit); therefore any value >= 32 would get truncated.
