Summary
ASoC: codec: sma1307: Fix memory corruption in sma1307_setting_loaded()
Details

In the Linux kernel, the following vulnerability has been resolved:

ASoC: codec: sma1307: Fix memory corruption in sma1307settingloaded()

The sma1307->set.header_size is how many integers are in the header (there are 8 of them) but instead of allocating space of 8 integers we allocate 8 bytes. This leads to memory corruption when we copy data it on the next line:

    memcpy(sma1307->set.header, data,
           sma1307->set.header_size * sizeof(int));

Also since we're immediately copying over the memory in ->set.header, there is no need to zero it in the allocator. Use devmkmallocarray() to allocate the memory instead.
