Message-ID: <20120616131904.GA17980@elgon.mountain> (raw)

Hello Ola Lilja,

The patch 679d7abdc754: "ASoC: codecs: Add AB8500 codec-driver" from
Jun 7, 2012, leads to the following Sparse warnings:

sound/soc/codecs/ab8500-codec.c:1960:53:
	warning: cast truncates bits from constant value (1013 becomes 13)
sound/soc/codecs/ab8500-codec.c:1968:53:
	warning: cast truncates bits from constant value (1013 becomes 13)

sound/soc/codecs/ab8500-codec.c
  1958          /* Set DMic-clocks to outputs */
  1959          status = abx500_get_register_interruptible(codec->dev, (u8)AB8500_MISC,
  1960                                                  (u8)AB8500_GPIO_DIR4_REG,
                                                            ^^^^^^^^^^^^^^^^^^^^
  1961                                                  &value8);
  1962          if (status < 0)
  1963                  return status;
  1964          value = value8 | GPIO27_DIR_OUTPUT | GPIO29_DIR_OUTPUT |
  1965                  GPIO31_DIR_OUTPUT;
  1966          status = abx500_set_register_interruptible(codec->dev,
  1967                                                  (u8)AB8500_MISC,
  1968                                                  (u8)AB8500_GPIO_DIR4_REG,
                                                        ^^^^^^^^^^^^^^^^^^^^^^^^
  1969                                                  value);

In my quick check we only seem to use the truncated values of these
defines so I'm not sure this was intended.

regards,
dan carpenter
