    Data allocated with devm_ioremap or devm_ioremap_nocache should not be
    freed using iounmap, because doing so causes a dangling pointer, and a
    subsequent double free.

    The semantic match that finds this problem is as follows:

    //
    @r@
    expression x;
    @@
    (
    x = devm_ioremap(...)
    |
    x = devm_ioremap_nocache(...)
    )

    @@
    expression r.x;
    @@
    * iounmap(x)

    The enable function was using the global timeout variable for local operations.
    This resulted in the value of the global variable being corrupted, thus
    breaking the code.
