Compiling error rtw_get_systime_us

[Tymofei]

Im very new to linux with basic c knowledge.There was lot more issues but i fixed most of them but that last one driving me crazy.

/home/kali/rtl8188eus/os_dep/linux/ioctl_cfg80211.c: In function ‘rtw_get_systime_us’: /home/kali/rtl8188eus/os_dep/linux/ioctl_cfg80211.c:706:1: warning: no return statement in function returning non-void [-Wreturn-type] 706 | } | ^

i got into .c file and checked the fucntion but didnt get whats wrong its seems like it returns void but whats the problem thenn ??
