[alsa-devel] [PATCHv2] ASoC: Intel: Fix sparse warnings for firmware loader.

[Liam Girdwood]

Changes since V1 :-
 o Fixed sparse warning for block_module_remove
 o Fixed additional sparse warnings when building entire driver. 

Sparse gives us the following warnings on sst-firmware.c

  CHECK   sound/soc/intel/sst-firmware.c
sound/soc/intel/sst-firmware.c:39:34: warning: incorrect type in argument 1 (different address spaces)

sound/soc/intel/sst-firmware.c:430:5: warning: symbol 'sst_block_module_remove' was not declared. Should it be static?
