[PATCH 01/12] crypto: atmel-ecc - rename driver_data before moving it into atmel-i2c

[Lothar Rubusch]

Rename the local driver_data instance to atmel_i2c_mgmt in
preparation for moving the shared I2C client management
infrastructure into the atmel-i2c core driver in a subsequent
change.

No functional changes intended.
