dmaengine: stm32-dma: Fix PM usage counter imbalance in stm32 dma ops
stable inclusion from stable-5.10.58 commit bbce3c99f6226b2aafe21ce29b3cb186ae9ade29 bugzilla: 176984 https://gitee.com/openeuler/kernel/issues/I4E2P4 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=bbce3c99f6226b2aafe21ce29b3cb186ae9ade29 -------------------------------- [ Upstream commit d54db74a ] pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. We fix it by replacing it with pm_runtime_resume_and_get to keep usage counter balanced.
