stable inclusion from stable-v5.10.106 commit 2c6a75ea32f99ba4b315d7b58f579493d7ac2a9a bugzilla: https://gitee.com/openeuler/kernel/issues/I573US
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit cc71d37fd1f11e0495b1cf580909ebea37eaa886 ]
The driver creates the top row map sysfs attribute in input_configured() method; unfortunately we do not have a callback that is executed when HID interface is unbound, thus we are leaking these sysfs attributes, for example when device is disconnected.
To fix it let's switch to managed version of adding sysfs attributes which will ensure that they are destroyed when the driver is unbound.
