Revision d81916910f7498fe7a768697e0101d488f9fe665 authored by Yang Yingliang on 29 October 2022, 08:29:31 UTC, committed by Huacai Chen on 29 October 2022, 08:29:31 UTC
Currently the return value of 'sub_driver->init' is not checked. If sparse_keymap_setup() called in the init function fails, 'generic_ inputdev' is freed, then it will lead a UAF when using it in generic_ acpi_laptop_init(). Fix it by checking the return value and setting generic_inputdev to NULL after free, so as to avoid double free it. The error code in generic_subdriver_init() is always negative, so the return of generic_subdriver_init() can be simplified.
