Hi, All
The mainline patch to fix CVE-2024-50282 add a check to fix a potential buffer overflow issue in amdgpu_debugfs_gprwave_read() which is introduced in commit 553f973a0d7b ("drm/amd/amdgpu: Update debugfs for XCC support (v3)"), but some linux-stable fix patches add the check in some other funcitons, is something wrong here?
