Enabling twice leaks a runtime PM\nreference, preventing the device from ever suspending again;\ndisabling twice underflows the usage count and triggers a\n\"Runtime PM usage count underflow\" warning.\n\nBail out early when the requested state matches the current state.\nWhile at it, switch to pm_runtime_resume_and_get() so a failed\nresume is propagated to userspace instead of silently marking the\nevent enabled.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/0fc740c25c9abb25113398ebb58e2f2ce57741a7","tags":[]},{"url":"https://git.kernel.org/stable/c/470edb012b1d9a4fba1cd59e329e60f0798c791a","tags":[]},{"url":"https://git.kernel.org/stable/c/56fe8e5f313a64e458bb6f8b982de925345e21a7","tags":[]},{"url":"https://git.kernel.org/stable/c/579c049b4cb6fc72ce2c505fc5334540be0efcd3","tags":[]},{"url":"https://git.kernel.org/stable/c/685d9d1e5c47e024413981fb7eddab86132b04a1","tags":[]},{"url":"https://git.kernel.org/stable/c/70b9482926ca92862460e659f5e5fde99ae0b4fa","tags":[]},{"url":"https://git.kernel.org/stable/c/8e76ab81319858736ccf23141e9415f9a1869337","tags":[]},{"url":"https://git.kernel.org/stable/c/b2d7a97d75b648a643f60d77f4d6d70161268855","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
