If anyone has any objections, please let me know. ------------------ From: Koichiro Den [ Upstream commit c0d9c6275adcca7c0ca5f4270bf88026f9864bd1 ] terminate_all() can finish immediately when the channel is unconfigured, paused, idle, or already stopped in hardware. A pending PAUSE request can survive these paths and block issue_pending() even after termination. Clear the request whenever termination leaves the channel idle. A running channel keeps its STOP request until the interrupt handler consumes it.
