Following build warnings noticed while building arm64 with allmodconfig
on stable-rc 5.4 with gcc-8 and gcc-12 toolchains.
Reported-by: Linux Kernel Functional Testing <lkft@xxxxxxxxxx>
drivers/gpu/drm/mediatek/mtk_drm_gem.c: In function 'mtk_drm_gem_prime_vmap':
drivers/gpu/drm/mediatek/mtk_drm_gem.c:273:10: warning: returning
'int' from a function with return type 'void *' makes pointer from
integer without a cast [-Wint-conversion]

For the Linux-5.4 kernel, we should use "return -ERR_PTR(-ENOMEM)" instead of "return -ENOMEM".
Since, newer version kernel prefer to return error code instead of error pointer.
See below commit for more information.
