Subject: [PATCH] drm/gma500: fix memory leaks

In mdfld_dsi_output_init(), if mdfld_dsi_pkg_sender_init() fails, the
execution is directed to the 'dsi_init_err0' label. However, some
previously allocated buffers and resources are not deallocated, leading to
memory/resource leaks. To fix this issue, revise the 'dsi_init_err0' label.
