On version 11 of the "drm/panic: Add a drm panic handler" series [1], Thomas
suggested to change the name of the function `drm_panic_gem_get_scanout_buffer`
to `drm_fb_dma_get_scanout_buffer` and this request was applied on version 12,
which is the version that landed [2]. Although the name of the function
changed on the C file, it didn't changed on the header file, leading to a
compilation error as such:
drivers/gpu/drm/imx/ipuv3/ipuv3-plane.c:780:24: error: use of undeclared
identifier 'drm_fb_dma_get_scanout_buffer'; did you mean 'drm_panic_gem_get_scanout_buffer'?
780 | .get_scanout_buffer = drm_fb_dma_get_scanout_buffer,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| drm_panic_gem_get_scanout_buffer
./include/drm/drm_fb_dma_helper.h:23:5: note: 'drm_panic_gem_get_scanout_buffer'
declared here
23 | int drm_panic_gem_get_scanout_buffer(struct drm_plane *plane,
| ^
1 error generated.
Fix the compilation error by changing `drm_panic_gem_get_scanout_buffer` to
`drm_fb_dma_get_scanout_buffer` on the header file.
