   4 Subject: [PATCH] tinypcminfo: make function pcm_get_format_name() static
   5
   6 When building tinyalsa with gcc 5.x, the following warnings appear:
   7
   8 tinypcminfo.c:97:52: warning: 'format_lookup' is static but used in inline function 'pcm_get_format_name' which is not static
   9      return bit_index < ARRAY_SIZE(format_lookup) ? format_lookup[bit_index] : NULL;
  10                                                     ^
  11 tinypcminfo.c:97:35: warning: 'format_lookup' is static but used in inline function 'pcm_get_format_name' which is not static
  12      return bit_index < ARRAY_SIZE(format_lookup) ? format_lookup[bit_index] : NULL;
  13
  14 And the build fails with:
  15
  16 tinypcminfo.o: In function `main':
  17 tinypcminfo.c:(.text+0x2f0): undefined reference to `pcm_get_format_name'
  18 collect2: error: ld returned 1 exit status
  19
  20 To fix this, this patch marks the pcm_get_format_name() as static,
  21 since it's anyway only used in tinypcminfo.c.
