And you are leaking memory here...He's not, dev_get_regmap() just gets a pointer to an existing regmap - no reference is taken and nothing is allocated. It's a helper that's mainly there so that generic code can be written without needing the regmap to be passed around. The caller is responsible for ensuring that it will stick around for as long as it's used (generally by having it lifetime managed with the device).
I was not talking about data returned by dev_get_regmap() but all other memory that was allocated before as this was pre devm conversion of the driver. Thanks. -- Dmitry
