ipq806x_data is not used outside this file, so it can be static. Fixes the following sparse warning: sound/soc/qcom/lpass-ipq806x.c:76:22: warning: symbol 'ipq806x_data' was not declared. Should it be static? Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Mark Brown <broonie@kernel.org>
