Normally, the type of enums is "unsigned int" or "int". GCC has the "-fshort-enums" option, which instructs the compiler to use the smallest data type that can hold all the values in the enum (i.e: char, short, int or their unsigned variants). According to the GCC documentation, "-fshort-enums" may be default on some targets. This seems to be the case for SOF when built for a certain 32-bit ARM platform. On Linux, this is not the case (tested with "aarch64-linux-gnu-gcc") which means enums such as "enum sof_comp_type" will end up having different sizes on Linux and SOF. Since "enum sof_comp_type" is used in IPC-related structures such as "struct sof_ipc_comp", this means the fields of the structures will end up being placed at different offsets. This, in turn, leads to SOF not being able to properly interpret data passed from Linux. With this in mind, replace "enum sof_comp_type" from "struct sof_ipc_comp" with "uint32_t".
