Documentation: ACPI: EINJ: Fix obsolete example
commit 9066e151c37950af92c3be6a7270daa8e8063db9 upstream.
Since commit 488dac0c9237 ("libfs: fix error cast of negative value in
simple_attr_write()"), the EINJ debugfs interface no longer accepts
negative values as input. Attempt to do so will result in EINVAL.
Fixes: 488dac0c9237 ("libfs: fix error cast of negative value in simple_attr_write()")
