-Subject: [PATCH] Fixes a problem when module probes before i2c
- module is available
-
-The driver crashed while a NULL pointer returned by i2c_get_adapter()
-has been used to access the i2c bus functions.
-The headphone probing function hb_hp_probe() now returns -EPROBE_DEFER
-in case the i2c module has not been loaded yet.
