ECC counter structures are freed without removing the node from the stats_list. This can lead to invalid access due to dangling pointers. Update the ecc counter free logic to set them to NULL upon free, to remove them from stats_list and free them by validation. Also updated some of the ecc init paths where error was not propa- gated to callers and full ecc counters deallocation was not done. Now, calling unit ecc_free from any context (with counters alloc- ated or not) is harmless as requisite checks are in place. bug 3326612 bug 3345977 Change-Id: I05eb6ed226cff9197ad37776912da9dcb7e0716d Signed-off-by: Sagar Kamble <skamble@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nvgpu/+/2565264 Tested-by: Ashish Mhetre <amhetre@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com> Reviewed-by: svc_kernel_abi <svc_kernel_abi@nvidia.com> Reviewed-by: Konsta Holtta <kholtta@nvidia.com> Reviewed-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> GVS: Gerrit_Virtual_Submit
