It needs to be explicit that this happens _before_ firmware-N.bin and board-M.bin loading. As such, you can't add a quirk to the firmware.bin (a standard way to handle firmware issues). > For example, firmware build on Xiaomi Poco F1 (sdm845) phone: > "QC_IMAGE_VERSION_STRING=WLAN.HL.2.0.c3-00257-QCAHLSWMTPLZ-1" > > If we do not skip the host cap QMI request on Poco F1, then we get a > QMI_ERR_MALFORMED_MSG_V01 error message before loading the firmware in the > ath10k_qmi_host_cap_send_sync().
