2019-04-25ASoC: stm32: i2s: return the get_irq errorFabien Dessenne
During probe, return the "get_irq" error value instead of -ENOENT. This allows the driver to be deferred probed if needed. Signed-off-by: Fabien Dessenne <fabien.dessenne@st.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-04-10ASoC: stm32: sai: fix master clock managementOlivier Moysan
When master clock is used, master clock rate is set exclusively. Parent clocks of master clock cannot be changed after a call to clk_set_rate_exclusive(). So the parent clock of SAI kernel clock must be set before. Ensure also that exclusive rate operations are balanced in STM32 SAI driver.
