We have a use case in the at24 EEPROM driver (recently converted to using regmap instead of raw i2c/smbus calls) where we read from/write to the regmap in a loop, while protecting the entire loop with a mutex. Currently this implicitly makes us use two mutexes - one in the driver and one in regmap. While browsing the code for similar use cases I noticed a significant number of places where locking *seems* redundant. Allow users to completely disable any locking mechanisms in regmap config.
