Subject: I2C: mv64xxx: move mv64xxx_i2c_prepare_for_io()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3420afbc06058c9c13f7d69cf48b9d5429db6bd9;p=linux-beck.git

I2C: mv64xxx: move mv64xxx_i2c_prepare_for_io()

Move mv64xxx_i2c_prepare_for_io() higher up in the driver to avoid a
future forward declaration for this function.
