/// ioctl: "get abs value/limits"

/// `abs` should be one of the "Absolute axes" values defined in the Linux kernel headers.
/// In modern (5.11) kernels these are in `include/uapi/linux/input-event-codes.h`, and in older
/// kernels these defines can be found in `include/uapi/linux/input.h`

/// # Panics
///
/// Calling this with a value greater than the kernel-defined `ABS_MAX` (typically 0x3f) will panic.
///
/// # Safety
///
/// 'abs' must be a valid axis number and supported by the device, otherwise the behavior is
/// undefined.
