It is good to fix lint, but if you fix lint on unrelated features in your patch, it makes your patch that much harder to merge.  Since you're modifying the self timer code, your patch will only apply after the self timer patch lands.  But if you had just left this code alone, it would not have mattered which one came first.

Thanks for fixing the space issue. Note, however, that the indentation is too deep. 2-space indentation, please.
