Akinobu Mita bf0c25cb3d lib/notifier-error-inject: fix error when writing -errno to debugfs file
[ Upstream commit f883c3edd2 ]

The simple attribute files do not accept a negative value since the commit
488dac0c92 ("libfs: fix error cast of negative value in
simple_attr_write()").

This restores the previous behaviour by using newly introduced
DEFINE_SIMPLE_ATTRIBUTE_SIGNED instead of DEFINE_SIMPLE_ATTRIBUTE.

Fixes: 488dac0c92 ("libfs: fix error cast of negative value in simple_attr_write()")
