HID: hid-input: fix stylus battery reporting
[ Upstream commit 505f394fa239cecb76d916aa858f87ed7ea7fde4 ]
With commit 4f3882177240 hid-input started clearing of "ignored" usages
to avoid using garbage that might have been left in them. However
"battery strength" usages should not be ignored, as we do want to
use them.
