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.
