Johan Hovold e144ed28be USB: cdc-acm: fix write and resume race ... Fix race between write() and resume() due to improper locking that could lead to writes being reordered. Resume must be done atomically and susp_count be protected by the write_lock in order to prevent racing with write(). This could otherwise lead to writes being reordered if write() grabs the write_lock after susp_count is decremented, but before the delayed urb is submitted.
