This function is used by dev_get_regmap() to retrieve a regmap for the specified device. If the device has more than one regmap, the name parameter can be used to specify one. The code here uses a pointer comparison to check for equal strings. This however will probably always fail, as the regmap->name is allocated via kstrdup_const() from the regmap's config->name. Fix this by using strcmp() instead.
