rtl8852be_bt's Issues

Error during 'make' on Pop OS (22.04, Kernel 5.17.5-76051705-generic)

I get an error during the process trying to use this in Pop OS (22.04, Kernel 5.17.5-76051705-generic). The error I get is as follows:

make -C /lib/modules/5.17.5-76051705-generic/build M=/home/recovery/rtl8852be_bt modules
make[1]: Entering directory '/usr/src/linux-headers-5.17.5-76051705-generic'

Attempted with Ubuntu (22.04, Kernel 5.15.0-41-generic) on the same hardware, and 'make' completes fine.

Solution not working on 5.13 kernel

Hello! Can you help me out? I tried to reproduce your solution from your commits using kernel 5.13 (ubuntu 20.04) but bluetooth still doesn`t work. Behavior is that bluetooth shows up on the system, but never finds any devices while scanning. I tried many different bluetooth devices which are working.
