[alsa-devel] [PATCH] ASoC: samsung: ASoC: samsung: Fix IISMOD setting in i2s_set_sysclk()

[Padmavathi Venna]

In the i2s_set_sysclk() callback we are currently clearing all bits
of the IISMOD register in i2s_set_sysclk. It's due to an incorrect
mask used for the AND operation which is introduced in commit
a5a56871f804edac93a53b5e871c0e9818fb9033 (ASoC: samsung:
add support for exynos7 I2S controller) and also adds the missing
break statement.
