Function riot_wrappers::interrupt::free

pub fn free<R, F: FnOnce(&CriticalSection<'_>) -> R>(f: F) -> R

Run a closure in the current context, but with interrupts disabled.

The function gets passed a bare_metal::CriticalSection attesting to the fact that interrupts are off.

This is equivalent to the cortex_m crate function of the same name.
