Hello mate,

I was obtaining the same issue.

My environment:

• OS Name: Ubuntu 20.04.1 LTS x64 bits
  $ cat /proc/version
Linux version 5.4.0-42-generic (buildd@lgw01-amd64-038)
(gcc version 9.3.0 (Ubuntu 9.3.0-10ubuntu2))
#46-Ubuntu SMP Fri Jul 10 00:24:02 UTC 2020

To solve the issue that you are reporting try the following:

https://askubuntu.com/questions/1047832/tp-link-tl-wn725n-driver-for-18-04-version

# Check if the driver is installed
$ lsmod | grep 8188

DISCLAIMER This solution use another github's repository.

Try to edit code in "include/osdep_service.h" with the help of this answer https://qna.habr.com/q/517043.

1)Add at 22nd line
#include <linux/timer.h>

2)After 293rd line add
timer_setup(ptimer, pfunc, (u32)cntx);

3)And remove this:
ptimer->function = pfunc;
ptimer->data = (unsigned long)cntx;
init_timer(ptimer);
