cc1: error: incompatible gcc/plugin versions

my dkms build is failing after updating the kernel

this repository was working:

https://github.com/morrownr/8821cu-20210118

when trying to do it manually

$ make
make ARCH=i386 CROSS_COMPILE= -C /lib/modules/5.16.12-arch1-1.0/build M=/home/user/Downloads/8821cu/8821cu-20210118  modules
make[1]: Entering directory '/usr/lib/modules/5.16.12-arch1-1.0/build'
  CC [M]  /home/user/Downloads/8821cu/8821cu-20210118/core/rtw_cmd.o
cc1: error: incompatible gcc/plugin versions
cc1: error: failed to initialize plugin ./scripts/gcc-plugins/structleak_plugin.so
make[2]: *** [scripts/Makefile.build:287: /home/user/Downloads/8821cu/8821cu-20210118/core/rtw_cmd.o] Error 1

$ uname -a
Linux router 5.16.12-arch1-1.0 #1 SMP PREEMPT Fri, 04 Mar 2022 13:50:58 +0000 i686 GNU/Linux

$ cat /proc/version
Linux version 5.16.12-arch1-1.0 (linux@archlinux) (gcc (GCC) 11.2.0, GNU ld (GNU Binutils) 2.38) #1 SMP PREEMPT Fri, 04 Mar 2022 13:50:58 +0000

$ pacman -Q gcc
gcc 11.2.0-3.4

$ gcc --version | head -n 1
gcc (GCC) 11.2.0

$ pacman -Q binutils
binutils 2.38-3.9

$ pacman -Q bc
bc 1.07.1-4.0

the error seems to point to different version used to compile the kernel, yet my gcc version seems to match. any ideas?

Re: cc1: error: incompatible gcc/plugin versions

Reads like a dupliciate of this one.  But it's useful to know that there are two of you out there building dkms kernel modules.  I see you're building a kernel module to support an out of kernel source for a USB Wifi driver.  I'll just note that I'm running a realtek 8811 chipset based usb device on my arch32 laptop, and a realtek 8812 chipset based PCI-e card on my video server, and these are working just fine from kernel sources. I guess the 8811, 8821 and 8831 are just too weird to be in kernel, or maybe the letters after the number are important because mine are EUS and US respectively.
