There is a newer version of this series
[PATCH v6 1/2] Bluetooth: btqca: move WCN7850 workaround to the caller
Posted by Shuai Zhang 2 days, 16 hours ago 
WCN7850 will first attempt to use ELF_TYPE_PATCH,
and if that fails, it will fall back to TLV_TYPE_PATCH.

To code uniformity, move WCN7850 workaround to the caller.

You can keep the `if (err < 0) {` here.
