ASoC: xtfpga-i2s: Add missing __rcu annotation
tx_substeam is accessed using the RCU API and hence should have the __rcu annotation. Fixes the following sparse warnings: sound/soc/xtensa/xtfpga-i2s.c:165:24: error: incompatible types in comparison expression (different address spaces) sound/soc/xtensa/xtfpga-i2s.c:165:24: error: 'struct snd_pcm_substream [noderef] <asn:4>*' versus sound/soc/xtensa/xtfpga-i2s.c:165:24: error: 'struct snd_pcm_substream *' sound/soc/xtensa/xtfpga-i2s.c:255:24: error: incompatible types in comparison expression (different address spaces) sound/soc/xtensa/xtfpga-i2s.c:255:24: error: 'struct snd_pcm_substream [noderef] <asn:4>*' versus sound/soc/xtensa/xtfpga-i2s.c:255:24: error: 'struct snd_pcm_substream *' Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
