Remove the loop in rtw_pwr_wakeup that waits while the system is suspended. pwrpriv->bInSuspend is set in rtw_suspend and cleared in rtw_resume. These functions are the .suspend and .resume functions of the struct usb_driver for r8188eu. A usb_driver's suspend and resume functions are called when the entire system goes into suspend or runtime suspend. All of the code paths for rtw_pwr_wakeup start at ioctl handlers. We can remove the loop that checks bInSuspend. It's not possible to call an ioctl while the entire system is suspended. Signed-off-by: Martin Kaiser <martin@xxxxxxxxx> --- I tried to track down who calls suspend and resume of an usb_driver. My understanding is that all of these calls come from the pm layer and that the suspend and resume affects the whole system, not just the usb device. drivers/staging/r8188eu/core/rtw_pwrctrl.c | 4 ---- 1 file changed, 4 deletions(-) diff --git a/drivers/staging/r8188eu/core/rtw_pwrctrl.c b/drivers/staging/r8188eu/core/rtw_pwrctrl.c index 717a9bb26c19..093794414d67 100644 --- a/drivers/staging/r8188eu/core/rtw_pwrctrl.c +++ b/drivers/staging/r8188eu/core/rtw_pwrctrl.c @@ -369,10 +369,6 @@ int rtw_pwr_wakeup(struct adapter *padapter) while (pwrpriv->ps_processing && time_before(jiffies, timeout)) msleep(10); - /* System suspend is not allowed to wakeup */ - while (pwrpriv->bInSuspend && time_before(jiffies, timeout)) - msleep(10); - /* I think this should be check in IPS, LPS, autosuspend functions... */ if (check_fwstate(pmlmepriv, _FW_LINKED)) goto exit; -- 2.30.2
