Okay, here it is:

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The variable ret_val is used but not declared. This causes
the following compile error:

sound/soc/mid-x86/sst_platform.c: In function ‘sst_platform_open’:
sound/soc/mid-x86/sst_platform.c:274:2: error: ‘ret_val’ undeclared (first use in this function)
sound/soc/mid-x86/sst_platform.c:274:2: note: each undeclared identifier is reported only once for each function it appears in
make[1]: *** [sound/soc/mid-x86/sst_platform.o] Error 1

Fix this.
