If anyone has any objections, please let me know. ------------------ From: Krzysztof Kozlowski commit 141050cf3d84fc303df58796d68dc1376b0e8f67 upstream. During probe the driver allocates two dummy I2C devices for subchips in function pm800_pages_init(). Additionally this function allocates regmaps for these subchips. If any of these steps fail then these dummy I2C devices are not freed and resources leak. On pm800_pages_init() fail the driver must call pm800_pages_exit() to unregister dummy I2C devices.
