Technically the braces you remove in this patch _are_
unnecessary. But, I think the driver is more confusing
with them removed.
In a lot of places there is quite a bit of code between
where the opening and closing braces would be.
Granted, a lot of them are due to the wordy comments
but some are in places like:
for (...)
if (...) {
...
}
There aren't too bad but the one like this are:
If (...)
If (...)
...
else
...
else
...
The nested if/else blocks are easy to break.
Just my two cents...
