Abdun Nihaal 1b102d2cc4 regmap: fix potential memory leak of regmap_bus ... [ Upstream commit c871c199ac ] When __regmap_init() is called from __regmap_init_i2c() and __regmap_init_spi() (and their devm versions), the bus argument obtained from regmap_get_i2c_bus() and regmap_get_spi_bus(), may be allocated using kmemdup() to support quirks. In those cases, the bus->free_on_exit field is set to true. However, inside __regmap_init(), buf is not freed on any error path. This could lead to a memory leak of regmap_bus when __regmap_init() fails. Fix that by freeing bus on error path when free_on_exit is set.
