[ Upstream commit fb83610762dd5927212aa62a468dd3b756b57a88 ]
There are two pairs of declarations for thermal_cooling_device_register()
and thermal_of_cooling_device_register(), and only one set was changed
in a recent patch, so the other one now causes a compile-time warning:
drivers/net/wireless/mediatek/mt76/mt7915/init.c: In function 'mt7915_thermal_init':
drivers/net/wireless/mediatek/mt76/mt7915/init.c:134:48: error: passing argument 1 of 'thermal_cooling_device_register' discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]

Change the dummy helper functions to have the same arguments as the
normal version.
