> clkdev DEV ID information is limited to an array of 20 bytes
> (MAX_DEV_ID). It is possible that the ID could be longer than
> that. If so, the lookup will fail because the "real ID" will
> not match the copied value.
>
> For instance, generating a device name for the I2C Designware
> module using the PCI ID can result in a name of:
>
> i2c_designware.39424
>
> clkdev_create() will store:
>
> i2c_designware.3942
>
> The stored name is one off and will not match correctly during probe.
>
> Increase the size of the ID to allow for a longer name.
