Takashi Sakamoto d1a6fe41d3 ASoC: Intel: Skylake: fix invalid memory access due to wrong reference of pointer
In 'skl_tplg_set_module_init_data()', a pointer to 'params' member of
'struct skl_algo_data' is calculated, then casted to (u32 *) and assigned
to a member of configuration data. The configuration data is passed to the
other functions and used to process intel IPC. In this processing, the
value of member is used to get message data, however this can bring invalid
memory access in 'skl_set_module_params()' as a result of calculation of
a pointer for actual message data.

(sound/soc/intel/skylake/skl-topology.c)
skl_tplg_init_pipe_modules()
->skl_tplg_set_module_init_data() (has this bug)
->skl_tplg_set_module_params()
  (sound/soc/intel/skylake/skl-messages.c)
  ->skl_set_module_params()
    ((char *)param) + data_offset

This commit fixes the bug.
