Sry, but not sure you can :( These functions are not used by drivers directly because system suspend are not synchronized with PM runtime, so if you call pm_generic_runtime_suspend() and, at the same time, there is pm_runtime_get_() in progress --> race ... The pm_runtime_force_() APIs have to be used, or PM runtime drivers functions can be called directly, but only if it possible to be sure no other PM runtime calls active which is usually true at suspend_noirq stage. > > Remove the custom API that was used to ensure that the command > that is used to allow ELP during suspend is completed before the system > suspend. > > Signed-off-by: Eyal Reizer <eyalr@xxxxxx> > Signed-off-by: Tony Lindgren <tony@xxxxxxxxxxx> > --- > drivers/net/wireless/ti/wlcore/main.c | 51 +++++++-------------------- > 1 file changed, 13 insertions(+), 38 deletions(-) > > diff --git a/drivers/net/wireless/ti/wlcore/main.c b/drivers/net/wireless/ti/wlcore/main.c > --- a/drivers/net/wireless/ti/wlcore/main.c > +++ b/drivers/net/wireless/ti/wlcore/main.c > @@ -998,24 +998,6 @@ static int wlcore_fw_wakeup(struct wl1271 *wl) > return wlcore_raw_write32(wl, HW_ACCESS_ELP_CTRL_REG, ELPCTRL_WAKE_UP); > } > > -static int wlcore_fw_sleep(struct wl1271 *wl) [...] -- regards, -grygorii -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
