ASoC: zx296702-i2s: remove unused ‘format’
In zx_i2s_hw_params(), 'format' is initialized and assigned bits based on params_format, but never used. So remove it. sound/soc/zte/zx296702-i2s.c: In function ‘zx_i2s_hw_params’: sound/soc/zte/zx296702-i2s.c:228:21: warning: variable ‘format’ set but not used [-Wunused-but-set-variable] unsigned long val, format; Signed-off-by: Vinod Koul <vinod.koul@intel.com> Acked-by: Jun Nie <jun.nie@linaro.org> Signed-off-by: Mark Brown <broonie@kernel.org>
