Linux Driver Probe Sequence. a driver’s probe() may return a negative errno value to indicate that the driver did not bind to this device, in which case it should have. when the driver has successfully bound itself to that device, then probe() returns zero and the driver model code will finish its part of. the probe () function is a part of the struct i2c_driver structure, and is executed anytime, once an i2c device is instantiated. The device model is organized around three main data structures: My requirement is dr1 probe has to call first then dr2 probe can be called. This is a small guide for those who want to write kernel drivers for i2c or smbus devices, using. This operation will take place in the probe function, which is called when a new device is. platform drivers follow the standard driver model convention, where discovery/enumeration is handled outside.
