Hello list members,

In habanalabs' goya chip driver, (https://elixir.bootlin.com/linux/v5.4.21/source/drivers/misc/habanalabs/dev ice.c#L1057)

I can see cdev_init, cdev_add and class_create functions.

Cdev_init is called insde device_init_cdev and cdev_add is called from device_cdev_sysfs_add -> cdev_device_add.

I can see class_create being called too. But I couldn't find device_create function (which is used to make sysfs entry?)

Can anyone tell me where device_create is called? (or where alternative method is being used?)

Happens in the call to cdev_device_add()
