Subject: Re: [PATCH] drm/rockchip: cdn-dp: Remove redundant workarounds for firmware loading

I'm having issues relevant to this thread. I want to build my rtl8723ds driver into the kernel. When fw_loader tries to load rtw8723d_fw.bin, my sysfs isn't mounted. Ideally, I don't have to use the driver as a module, use initramfs, or build the firmware into the kernel. Please let me know if I can do anything to help with the efforts.
