Summary
drm/amd/display: Add null check for pipe_ctx->plane_state in dcn20_program_pipe
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Add null check for pipectx->planestate in dcn20programpipe

This commit addresses a null pointer dereference issue in the dcn20_program_pipe function. The issue could occur when pipe_ctx->plane_state is null.

The fix adds a check to ensure pipe_ctx->plane_state is not null before accessing. This prevents a null pointer dereference.

Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn20/dcn20hwseq.c:1925 dcn20programpipe() error: we previously assumed 'pipectx->plane_state' could be null (see line 1877)
