ar71xx: WNR612v2: fix kernel panic due to wrong Wifi LED init
Netgear WNR612v2 flashed with recent OpenWrt builds suffers from kernel
panic at boot during wireless chip initialization, making device
unusable:
ath: phy0: Ignoring endianness difference in EEPROM magic bytes.
ath: phy0: Enable LNA combining
CPU 0 Unable to handle kernel paging request at virtual address 1000fee1, epc == 801d08f0, ra == 801d0d90
Oops[#1]:
CPU: 0 PID: 469 Comm: kmodloader Not tainted 4.9.120 #0
[ ... register dump etc ... ]
Kernel panic - not syncing: Fatal exception
Rebooting in 1 seconds..
This simple patch fixes above error. It keeps LED table in memory after
kernel init phase for ath9k driver to operate correctly (__initdata
removed).
Also, another bug is fixed - correct array size is provided to function
that adds platform LEDs (this device has only 1 connected to Wifi chip)
preventing code from going outside array bounds.
Fixes: 1f5ea4eae46e ("ar71xx: add correct named default wireless led by using platform leds")
