I have a Dell Inspiron 15 3521 with a Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter inside. After an update the WiFi broke and I cannot seem to fix it. I tried to follow the steps from this thread where somebody has a similar problem to build the driver, but on make it gives me an error about redefinition of "kmalloc_array" even after
make clean (I tried to build it previously in fact). The device is not hardware blocked,
rfkill list outputs:
0: dell-wifi: Wireless LAN Soft blocked: no Hard blocked: no 1: dell-bluetooth: Bluetooth Soft blocked: no Hard blocked: no 2: hci0: Bluetooth Soft blocked: no Hard blocked: no
lshw -C network displays this as a result for the wifi adapter.

and there is no driver=ath9k or whatever it must be.
lsmod |grep mac80211 gives the following result:

How can I fix this?
Edit2: uname -r outputs
lspci -nn |grep 0280 outputs
