From: Zhang Zekun <zhangzekun11@xxxxxxxxxx> This reverts commit 25d7e84343e1235b667cf5226c3934fdf36f0df6. The origin mainline patch fix a buffer overflow issue in amdgpu_debugfs_gprwave_read(), but it has not been introduced in kernel 6.1 and older kernels. This patch add a check in a wrong function in the same file.
