This is a single patch that attempts to address a 13-year-old TODO in the adreno GPU driver by calling `recover()` when a ringbuffer drain timeout occurs in `adreno_idle()`. While the intent is reasonable, the implementation has **serious problems** that would likely cause kernel crashes, deadlocks, or other undefined behavior. The `recover()` path is designed to be called from `recover_worker()` under specific locking and state management conditions that are not met when calling it directly from `adreno_idle()`.
**Not suitable for merging as-is.** The approach needs significant rethinking.
