Unknown symbol vb2_vmalloc_memops

[0x5e]

Hi, I'm trying to build & run akvcam in alpine, when modprobe akvcam, dmesg says: "Unknown symbol vb2_vmalloc_memops".
I'm not familiar with linux kernel, ChatGPT tells me I should load videobuf2_vmalloc first, either manually run modprobe videobuf2_vmalloc or add request_module("videobuf2_vmalloc") in akvcam init function. Will it be better adding request_module("videobuf2_vmalloc") into this project?

Try adding request_module("videobuf2_vmalloc"); here and check if it works.
