From: Shuai Xue <xueshuai@linux.alibaba.com> stable inclusion from stable-v6.6.92 commit d530dd65f6f3c04bbf141702ecccd70170ed04ad category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICGTHF Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit a409e919ca321cc0e28f8abf96fde299f0072a81 upstream. The idxd_cleanup() helper cleans up perfmon, interrupts, internals and so on. Refactor remove call with the idxd_cleanup() helper to avoid code duplication. Note, this also fixes the missing put_device() for idxd groups, enginces and wqs.
