SND_SOC_COMPONENT_UP(9)                        ASoC                       SND_SOC_COMPONENT_UP(9)



NAME
       snd_soc_component_update_bits_async - Perform asynchronous read/modify/write cycle

SYNOPSIS
       int snd_soc_component_update_bits_async(struct snd_soc_component * component,
                                               unsigned int reg, unsigned int mask,
                                               unsigned int val);

ARGUMENTS
       component
           Component to update

       reg
           Register to update

       mask
           Mask that specifies which bits to update

       val
           New value for the bits specified by mask

DESCRIPTION
       This function is similar to snd_soc_component_update_bits, but the update operation is
       scheduled asynchronously. This means it may not be completed when the function returns. To
       make sure that all scheduled updates have been completed snd_soc_component_async_complete
       must be called.

RETURN
       1 if the operation was successful and the value of the register changed, 0 if the
       operation was successful, but the value did not change. Returns a negative error code
       otherwise.
