Subject: [PATCH] Documentation: ACPI: EINJ: Fix obsolete example
Git-commit: 9066e151c37950af92c3be6a7270daa8e8063db9
Patch-mainline: v6.0-rc1
References: git-fixes
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()")
