π sdca_asoc_populate_component β the kernel API manual, bestie edition β¨
okay so you found yourself in the 9 section of the Kernel API Manual, which means we're deep in kernel-land and honestly? iconic. today's main character is sdca_asoc_populate_component, and she's here to fill in a component driver for a Function. no cap. π
β¨ NAME β¨
sdca_asoc_populate_component β fill in a component driver for a Function
likeβ¦ literally what it says on the tin, bestie. it populates, it's a component driver, and the Function is the vibe. π¦
πΈ SYNOPSIS πΈ
int sdca_asoc_populate_component (struct device *dev , struct
sdca_function_data *function , struct snd_soc_component_driver
*component_drv , struct snd_soc_dai_driver **dai_drv , int *num_dai_drv
, const struct snd_soc_dai_ops *ops );
six arguments. six. she's highkey thorough and honestly we stan a thorough queen. π
π ARGUMENTS π
devβ Pointer to the device against which allocations will be done. so like, all the memory she grabs? it's going against this device. that's her whole allocation accountability partner. π«Άfunctionβ Pointer to the Function information. yes that's the DisCo info she's working from. she reads it, she respects it.component_drvβ Pointer to the component driver to be populated. this is the glow-up target, the one getting filled in. πdai_drvβ Pointer to the DAI driver array to be allocated and populated. note the double pointer, bestie β she's allocating it for you. πnum_dai_drvβ Pointer to integer that will be populated with the number of DAI drivers. so you know how many you got. counting is caring fr fr.opsβ DAI ops pointer that will be used for each DAI driver. one ops to rule them all, applied to every single DAI driver. β
π¦ DESCRIPTION π¦
okay so here's the tea β β this function populates a snd_soc_component_driver structure based on the DisCo information for a particular SDCA Function. and the way she does it? she does all allocation internally. you don't lift a finger, she handles the mallocs, you just vibe. no cap, that's main character energy right there. π
π RETURN π
Returns zero on success, and a negative error code on failure. so if you get 0, slay, you ate. if you get negative? that's a π moment, check your error code. periodt.
