    of/i2c: Fix module load order issue caused by of_i2c.c · 925bb9c6
    Grant Likely authored
    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.
