No, Linux logs nothing; the packets only show up in btmon:

  = Vendor Diagnostic (len 492)                      [hci0] 0.761331
          dc 2e e8 01 e4 01 03 00 0a ff 10 04 01 00 55 53  ..............US
  = Vendor Diagnostic (len 481)                     [hci0] 11.334015
          dc 2e dd 01 d9 01 04 00 0a ff 10 04 01 00 51 d3  ..............Q.

I will add this to the commit message in v2.

They are different builds with the same file name:

  OnePlus:        BTFM.CHE.2.1.4.c2-00002-QCACHROMZ-2.184841.1
                  (216380 bytes, built Jan 3 2019, shipped with OxygenOS)
  linux-firmware: BTFM.CHE.2.1.3.c7-00024-QCACHROM-1
                  (177060 bytes, built Dec 4 2018)

Both TLV headers report the same ROM build (0x0201) and patch version
(0x0002), so only the build label tells them apart. The controller
returns the OnePlus label when asked with EDL_GET_BUILD_INFO_CMD;
btqca does not send that for WCN3990, so it is not in the kernel log.

Thank you for the review.
