In preparation for varying the poweron error handling in function

Hi Dafna,
the braces were added as a way to increase human readability.
Not to bikeshed this, but the kernel style guide is clear about this.
No unneeded braces should be used where a single statement will do.
Hey Robert!
That's right, style rules come before personal preferences.
I'll send a v3 without the braces as soon as possible!
Cheers,
- Angelo
