Felipe, I am seeing all sorts of deadlocks now, after removing the workqueue (patch V2). Some have easy fixes, but for others it is not as obvious. The code was much simpler when I could just trigger a deferred worker function. Workqueues are used in at91_udc, lpc32xx_udc, mv_udc_core, and pch_udc. Could you please clarify why it is not OK to use one in bcm63xx_udc? Thanks. |
