Input: synaptics-rmi4 - propagate F54 worker errors to V4L2 queue
Previously, rmi_f54_buffer_queue() waited for the worker thread to
finish but ignored whether it succeeded. If the worker failed (e.g.,
due to a timeout or register read failure), the queue thread would
silently return success, delivering stale or uninitialized memory to
userspace.
Add a 'report_error' field to struct f54_data to store the worker's exit
status. Check this field in rmi_f54_buffer_queue() after the worker
finishes, and mark the buffer as VB2_BUF_STATE_ERROR if an error
occurred.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
