so its seems that the function drm_prime_sg_to_page_addr_arrays its not defined ..and others

Hello
I have fixed the drm_prime_sg_to_page_addr_arrays issue by "Xilinx/XRT#5943 hint.

Error

fl2000_drm/fl2000_gem.c:234:8: error: implicit declaration of function ‘drm_prime_sg_to_page_addr_arrays’; did you mean ‘drm_prime_sg_to_dma_addr_array’? [-Werror=implicit-function-declaration]
234 | ret = drm_prime_sg_to_page_addr_arrays(sgt, obj->pages, NULL, obj->num_pages);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| drm_prime_sg_to_dma_addr_array

Solution

Line 234 of the file fl2000_gem.c:
$ nano +234 fl2000_gem.c
Change:
ret = drm_prime_sg_to_page_addr_arrays(sgt, obj->pages, NULL, obj->num_pages);
To:
ret = drm_prime_sg_to_page_array(sgt, obj->pages, obj->num_pages);
