Subject: [PATCH] rtw88: extract: make 8822b an individual kernel module
Git-commit: 416e87fcc780cae8d72cb9370fa0f46007faa69a
Patch-mainline: v5.8-rc1
References: jsc#SLE-13430, bsc#1176741
Make objects about 8822b functions and 8822b tables,
i.e. rtw8822b.o and rtw8822b_table.o, an individual
kernel module called rtw88_8822b.ko.
For 8822b pcie chip, i.e. 8822BE chip, add a chip
entry point module called rtw88_8822be.ko which
will depend on rtw88_8822b.ko and rtwpci.ko.
