Bay trail, not work suspend on new kernels 4.14+ if wifi is enabled

[Kitsune]

If use kernel 4.14rc7 all is ok, but if use 4.14+ problem with suspend, if i'm enable wifi (broadcom, use bcmfmac driver) and press power button, i see black screen, low backlight, and tablet freezes. And can't efit from sleep. If wifi disabled, suspend/sleep work correctly, how fix this? Problem on all kernels 4.14, 4.15, 4.16, 4.17rc1.

I'm use this fix suspend patches

I also found this problem on a tablet bay trail

I bypassed 

with the  app Script Manager-Smanager creating a widget to the sleep.sh script

creating this script:

#!/system/bin/sh

svc wifi disable

sleep 1

rmmod r8723bs

sleep 1

su -c  echo 1 > /sys/power/pm_trace  &  echo  mem > /sys/power/state 

sleep 2

modprobe r8723bs

sleep 2

svc wifi enable

maybe you r8723bs module and superfluous to you

P.S.

another solution would be to modify the hex /sys/power/state string line in the libsuspend.so file.

but as you can see, they are barbaric "solutions" not at all elegant.

/libsuspend/autosuspend_wakeup_count.c

-#define SYS_POWER_STATE "/sys/power/state"

+#define SYS_POWER_STATE "/sys/power/state__________"

ours 8723bs needn't rmmod，suspend no problem.

but wlan0 wakeup，no network，have to reconnect wifi.

the eth0 wake up，network working，needn't reconnect.

you said which problem ? hub 1-0:1.0: Unbalanced pm_runtime_enable! usb usb1-port1: Unbalanced pm_runtime_enable，this problem ?
with “rtc: cmos” patch，the 8723bs bay trail devices suspend no problem on Ubuntu/debian，but Androidx86 must use “x86/platform, acpi” patch to make suspend and volume keys both work.

revert “rtc: cmos”，no the unbalanced problem on Androidx86，this must because Androidx86 rtc.

Second solution work? It disable sleep or what? Sleep will be work or no? I'm want that sleep work
