When devm_kasprintf() fails, it returns a NULL pointer. However, this return value is not properly checked in the function mt7996_thermal_init.
A NULL check should be added after the devm_kasprintf() to prevent potential NULL pointer dereference error.
Fixes: 69d54ce7491d0 ("switch to single multi-radio wiphy")
