| |
Hi, all
The mmc_sdio_init_card(drivers/mmc/core/sdio.c) function calls mmc_alloc_card(drivers/mmc/core/bus.c) function to allocate a card structure. card->dev.bus is assigned with mmc_bus_type in mmc_alloc_card function. Why not assign sdio_bus_type to card->dev.bus?
struct mmc_card *mmc_alloc_card(struct mmc_host *host, struct device_type *type) { struct mmc_card *card;
card = kzalloc(sizeof(struct mmc_card), GFP_KERNEL); if (!card) return ERR_PTR(-ENOMEM);
card->host = host;
device_initialize(&card->dev);
card->dev.parent = mmc_classdev(host); card->dev.bus = &mmc_bus_type; card->dev.release = mmc_release_card; card->dev.type = type;
return card; }
Thanks, Zhonghui
