Fixes camel casing for getDeviceID function. This includes an update to
the internal function variable 'deviceID' as it's relevant, needs updating,
and is clearly scoped to the small function.

First patch for me, so I chose a checkpatch.pl issue to get comfortable
with the workflow. Any and all nits welcome. 

Verified my change by recompiling and loading the module in question.
Additionaly, checkpatch.pl reports two fewer errors.
