stable inclusion from stable-5.10.52 commit 0c67c2e20366ec4c7a31259a8341a1896c217218 bugzilla: 175542 https://gitee.com/openeuler/kernel/issues/I4DTKU
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 81aad47278539f02de808bcc8251fed0ad3d6f55 ]
pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. Fix it by replacing it with pm_runtime_resume_and_get to keep usage counter balanced.
