Hello.
After upgrading the kernel(gentoo-sources), I can't scan and connect to wifi (I use wpa_supplicant).

Code:
$ uname -r
4.0.5-gentoo

Code:
$ lspci -k | grep -A2 Wireless
02:00.0 Network controller: Qualcomm Atheros AR9485 Wireless Network Adapter (rev 01)
   Subsystem: Samsung Electronics Co Ltd Device 410e
   Kernel driver in use: ath9k

Code:
$ dmesg | grep -i ath9k
[  +0,000034] ath9k 0000:02:00.0: enabling device (0000 -> 0002)
[  +1,016757] ath9k 0000:02:00.0 wlp2s0: renamed from wlan0

Code:
$ grep -i ath9k /usr/src/linux-4.0.5-gentoo/.config
CONFIG_ATH9K_HW=y
CONFIG_ATH9K_COMMON=y
# CONFIG_ATH9K_BTCOEX_SUPPORT is not set
CONFIG_ATH9K=y

# CONFIG_ATH9K_AHB is not set
# CONFIG_ATH9K_DEBUGFS is not set

# CONFIG_ATH9K_RFKILL is not set
# CONFIG_ATH9K_CHANNEL_CONTEXT is not set
