Hi all,

I am submitting two patches to fix null pointer dereference issues in
the AMD display driver.

1. Patch 1/2 (Fixes: 8e4ed3cf1642): Add null checks in
dcn20_program_pipe() to prevent potential crashes when accessing
plane_state.

2. Patch 2/2 (Fixes: 0baae6246307): Ensures pipe_ctx->plane_state is
checked in hwss_setup_dpp() to improve function stability.

Thanks for reviewing!
