of/i2c: Fix module load order issue caused by of_i2c.c
Commit 959e85f7, "i2c: add OF-style registration and binding" caused a module dependency loop where of_i2c.c calls functions in i2c-core, and i2c-core calls of_i2c_register_devices() in of_i2c. This means that when i2c support is built as a module when CONFIG_OF is set, then neither i2c_core nor of_i2c are able to be loaded. This patch fixes the problem by moving the of_i2c_register_devices() calls back into the device drivers. Device drivers already specifically request the core code to parse the device tree for devices anyway by setting the of_node pointer, so it isn't a big deal to also call the registration function. The drivers just become slightly more verbose. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Jean Delvare <khali@linux-fr.org>
