What happens if this file is opened twice and written in parallel ?
What if any
other attribute is accessed while the firmware download is ongoing ?
Good point. So you think I need to protect all with mutexes or there
is another way? From a quick look on other drivers i didn't see this
kind of protection (something to look at in the future)
