Hi, my name is Cristian, I'm writing from Chile

I'm trying to install the driver for my RTL8821CE card. I'm following
the instructions from the repo https://github.com/lwfinger/rtw88 (I
took the email from there) but when I try to run the "make" command, I
get the following error:

/home/cristian/Downloads/realtek_drivers/rtw88/main.c: In function
=E2=80=98rtw_core_init=E2=80=99:
/home/cristian/Downloads/realtek_drivers/rtw88/main.c:1623:2: error:
implicit declaration of function =E2=80=98tasklet_setup=E2=80=99
[-Werror=3Dimplicit-function-declaration]
 1623 |  tasklet_setup(&rtwdev->tx_tasklet, rtw_tx_tasklet);


this is the output from "sudo lshw -C network" and the full log of the erro=
r.
