interconnect: qcom: sm8450: Fix NULL pointer dereference in icc_link_nodes()
Summary
In the Linux kernel, the following vulnerability has been resolved: interconnect: qcom: sm8450: Fix NULL pointer dereference in icc_link_nodes() The change to dynamic IDs for SM8450 platform interconnects left two links unconverted, fix it to avoid the NULL pointer dereference in runtime, when a pointer to a destination interconnect is not valid: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008 <...> Call trace: icc_link_nodes+0x3c/0x100 (P) qcom_icc_rpmh_probe+0x1b4/0x528 platform_probe+0x64/0xc0 really_probe+0xc4/0x2a8 __driver_probe_device+0x80/0x140 driver_probe_device+0x48/0x170 __device_attach_driver+0xc0/0x148 bus_for_each_drv+0x88/0xf0 __device_attach+0xb0/0x1c0 device_initial_probe+0x58/0x68 bus_probe_device+0x40/0xb8 deferred_probe_work_func+0x90/0xd0 process_one_work+0x15c/0x3c0 worker_thread+0x2e8/0x400 kthread+0x150/0x208 ret_from_fork+0x10/0x20 Code: 900310f4 911d6294 91008280 94176078 (f94002a0) ---[ end trace 0000000000000000 ]--- Kernel panic - not syncing: Oops: Fatal exception
