Missing ! in gpio.rs

[allexoll]

I think there is a missing ! in gpio.rs in the gpio macro implementing is_high. see attached code for first occurence with missing ! and second occurence with ! present.

            impl<MODE> StatefulOutputPin for $PXx<Output<MODE>> {
                fn is_set_high(&self) -> Result<bool, Self::Error> {
                    let is_high = self.is_set_low()?;   // Missing "!"
                    Ok(is_high)
                }

                fn is_set_low(&self) -> Result<bool, Self::Error> {
                    // NOTE(unsafe) atomic read with no side effects
                    let is_low = unsafe { (*$GPIOX::ptr()).odr.read().bits() & (1 << self.i) == 0 };
                    Ok(is_low)
                }
            }

            impl<MODE> toggleable::Default for $PXx<Output<MODE>> {}

            impl<MODE> InputPin for $PXx<Output<MODE>> {
                type Error = void::Void;

                fn is_high(&self) -> Result<bool, Self::Error> {
                    let is_high = !self.is_low()?;     // Not missing
                    Ok(is_high)
                }

                fn is_low(&self) -> Result<bool, Self::Error> {
                    // NOTE(unsafe) atomic read with no side effects
                    let is_low = unsafe { (*$GPIOX::ptr()).idr.read().bits() & (1 << self.i) == 0 };
                    Ok(is_low)
                }
            }
