Examples are of IIO_TEMP channel having a generic scaling value, and another having IIO_MOD_TEMP_AMBIENT modifier with another scaling value. Previously the first scaling value for a channel type would be applied to all channels of like type in iio_generic_buffer Signed-off-by: Matt Ranostay Signed-off-by: Jonathan Cameron --- diff --git a/tools/iio/iio_utils.c b/tools/iio/iio_utils.c index 5eb6793f3972..7a6d61c6c012 100644 --- a/tools/iio/iio_utils.c +++ b/tools/iio/iio_utils.c @@ -121,10 +121,6 @@ int iioutils_get_type(unsigned *is_signed, unsigned *bytes, unsigned *bits_used, ret = -ENOENT; while (ent = readdir(dp), ent) - /* - * Do we allow devices to override a generic name with - * a specific one? - */ if ((strcmp(builtname, ent->d_name) == 0) || (strcmp(builtname_generic, ent->d_name) == 0)) { ret = asprintf(&filename, @@ -178,6 +174,13 @@ int iioutils_get_type(unsigned *is_signed, unsigned *bytes, unsigned *bits_used, sysfsfp = 0; free(filename); filename = 0; + + /* + * Avoid having a more generic entry overwriting + * the settings. + */ + if (strcmp(builtname, ent->d_name) == 0) + break; } error_close_sysfsfp:
