Hi all,
After merging the v4l-dvb-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:
drivers/media/pci/intel/ipu6/ipu6-mmu.c: In function 'ipu6_mmu_alloc':
drivers/media/pci/intel/ipu6/ipu6-mmu.c:541:28: error: implicit declaration of function 'vzalloc'; did you mean 'kzalloc'? [-Werror=implicit-function-declaration]
541 | mmu_info->l2_pts = vzalloc(ISP_L2PT_PTES * sizeof(*mmu_info->l2_pts));
| ^~~~~~~

drivers/media/pci/intel/ipu6/ipu6-mmu.c:541:26: error: assignment to 'u32 **' {aka 'unsigned int **'} from 'int' makes pointer from integer without a cast [-Werror=int-conversion]

Caused by commit
9163d83573e4 ("media: intel/ipu6: add IPU6 DMA mapping API and MMU table")
not including <linux/vmalloc.h>. It may have been exposed by commit
690da22dbfa8 ("asm-generic/io.h: kill vmalloc.h dependency")
from the mm-unstable branch of the mm tree, so I have applied the
following patch for today (and this or somthing like it should be applied
to the v4l-dvb-next tree).

Subject: [PATCH] media: intel/ipu6: explicitly include vmalloc.h
since this file uses vzalloc etc ...
