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 sof_ipc_ctrl_data) + sizeof(struct sof_ipc_ctrl_value_chan) *
le32_to_cpu(mc->num_channels)
with:
struct_size(scontrol->control_data, chanv, le32_to_cpu(mc->num_channels))
and so on...
This code was detected with the help of Coccinelle.
