Hi Rudraksha,

this is starting to look good, some remaining snags below:

Do not change the name of the function, it's confusing.
This is also used for setting the brightness of the torch, and after
this change it looks like the function is just for the flash.

Add a comment befor this that if we don't have a separate torch
enable pin connected, we use the flash pin also for the torch.
