This backports a patch from kernel 4.14 to the ath10k-ct version based on kernel 4.13. Some devices are using a user space script to load the calibration data from the flash and this was not trigged any more. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

Subject: [PATCH] ath10k: activate user space firmware loading again
|
|
|
|
In commit 9f5bcfe93315 ("ath10k: silence firmware file probing
|
|
warnings") the firmware loading was changed from request_firmware() to
|
|
request_firmware_direct() to silence some warnings in case it fails.
|
|
request_firmware_direct() directly searches in the file system only and
|
|
does not send a hotplug event to user space in case it could not find
|
|
the firmware directly.
|
|
In LEDE we use a user space script to extract the calibration data from
|
|
the flash memory which gets triggered by the hotplug event. This way the
|
|
firmware gets extracted from some vendor specific partition when the
|
|
driver requests this firmware. This mechanism does not work any more
|
|
after this change.
|
|
