Subject: [PATCH] spi: img-spfi: fix reference leak in img_spfi_resume
Git-commit: ee5558a9084584015c8754ffd029ce14a5827fa8
Patch-mainline: v5.11-rc1
References: git-fixes

pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to pm_runtime_put_noidle will result in
reference leak in img_spfi_resume, so we should fix it.
