Basically the thaw() callback wouldn't resume the device if the hibernation image was successfully created since the system would be powered off. This however isn't the correct flow for a system entering into s0i3 after the hibernation image is created. Some of the amdgpu callbacks have different behavior depending upon the intended state of the suspend. [How] Use pm_hibernation_mode_is_suspend() as an input to decide whether to run resume during thaw() callback.

[PATCH v6 03/10] KEYS: trusted: Fix memory leak in tpm2_load()

tpm2_load() allocates a blob indirectly via tpm2_key_decode() but it is not freed in all failure paths. Address this with a scope-based cleanup helper __free().
