As per commit c4f135d643823a86 ("workqueue: Wrap flush_workqueue() using a macro") says, use per "struct ath6kl_usb" workqueue. Signed-off-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> --- Changes in v3: Update patch description. Changes in v2: Use per "struct ath6kl_usb" workqueue instead of per module workqueue. This is a blind conversion, and is only compile tested. drivers/net/wireless/ath/ath6kl/usb.c | 16 ++++++++++++---- 1 file changed, 12 insertions(+), 4 deletions(-)
