[PATCH 5/9] ASoC: fsl: fsl_ssi: remove unnecessary tests

[Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>]

cppcheck warnings:

sound/soc/fsl/fsl_ssi.c:767:34: style: Condition 'div2' is always
false [knownConditionTrueFalse]
 stccr = SSI_SxCCR_PM(pm + 1) | (div2 ? SSI_SxCCR_DIV2 : 0) |

   ^

value is 0
 psr = 0;
       ^
sound/soc/fsl/fsl_ssi.c:768:4: note: Condition 'psr' is always false
  (psr ? SSI_SxCCR_PSR : 0);
   ^

Upon further analysis, the variables 'div2' and 'psr' are set to zero
and never modified. All the tests can be removed.
