Hi Zijun,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on bluetooth-next/master]
[also build test WARNING on linus/master v5.14-rc7 next-20210823]
[cannot apply to linux/master bluetooth/master]

I think the concept of 'vendor' (or 'factory' as it was named earlier) needs
more clarification.
Are we talking about USB BT modules with a the wcn6855 that are marketed by
the 'vendor'? If so, could the USB vendor it be used to determine the vendor?
Could modules from different vendors use the same firmware, even though it's
not the same for all vendors?.

Please also add your own Signed-off-by tag, even when sending unmodified
patches on behalf of others. In this case you are making changes to the
original patch and are effectively a co-author, which is another important
reason for adding the tag.

'separator' is part of the internal logic of this function, the caller
shouldn't have to care about it. Define it as a local variable instead
and initialize it to ''. If 'vendor' (or whatever it is called) is not
NULL assign 'separator' to '_'.

u16 board_id = le16_to_cpu(ver->board_id);
u32 rom_version = le32_to_cpu(ver->rom_version));
Then use these local variable instead of doing the endianness conversion
over and over again.
