The "fix" for this problem would be similar to commit 4265eb062a73 ("hwmon: (pc87360) Bounds check data->innr usage"). The change would be something like
- for (i = 0; i < data->tempnr; i++) { + for (i = 0; i < min(data->tempnr, ARRAY_SIZE(data->temp_max)); i++) {
but that would be purely random because the loop accesses several arrays indexed with i, and tempnr is never >= ARRAY_SIZE(data->temp_max). I kind of resist making such changes to the code just because the compiler is clueless.
Are we sprinkling the kernel code with code like this to make the compiler happy ?
