That leaves an unmatched runtime PM\nput and can trigger a runtime PM usage count underflow.\n\nFix this by making eh_noresume a regular bool so it can be accessed with\nREAD_ONCE() and WRITE_ONCE(). Snapshot it once per EH iteration and use\nthat snapshot for both runtime PM get and put decisions."
