[OpenWrt-Devel] [PATCH] mac80211: install new firmware for ath9k-htc on target

[Alexey Brodkin]

For quite some time new firmware for ath9k-htc devices
is available in
http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/ath9k_htc/

Moreover ath9k-htc kernel driver expects this new v1.4
firmware to exist in /lib/firmware/ath9k_htc.

What happens currently:
---------------------------->8--------------------------
[    7.830000] usb 1-1: ath9k_htc: Firmware ath9k_htc/htc_9271-1.4.0.fw
requested
[    7.840000] usb 1-1: Direct firmware load for
ath9k_htc/htc_9271-1.4.0.fw failed with error -2
[    7.850000] usb 1-1: Falling back to user helper
[    7.870000] usbcore: registered new interface driver ath9k_htc
[    7.880000] firmware ath9k_htc!htc_9271-1.4.0.fw:

[    7.890000] usb 1-1: ath9k_htc: Firmware htc_9271.fw requested
[    8.200000] usb 1-1: ath9k_htc: Transferred FW: htc_9271.fw, size:

[    8.440000] ath9k_htc 1-1:1.0: ath9k_htc: HTC initialized with 33

[   10.720000] ath9k_htc 1-1:1.0: ath9k_htc: FW Version: 1.3

[   10.760000] ieee80211 phy0: Atheros AR9271 Rev:1
---------------------------->8--------------------------

And with that patch new firmware is used instead:
