ALSA: pcm: oss: Use struct_size() helper
Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace the following form: sizeof(struct rate_priv) + src_format->channels * sizeof(struct rate_channel) with: struct_size(data, channels, src_format->channels) This code was detected with the help of Coccinelle.
