Subject: [PATCH] dma: ipu: Remove include/linux/dma/ipu-dma.h
When this file was renamed in commit b8a6d9980f75 ("dma: ipu: rename
mach/ipu.h to include/linux/dma/ipu-dma.h"), 4 .c files have been modified
accordingly:
drivers/dma/ipu/ipu_idmac.c
drivers/dma/ipu/ipu_irq.c
--> removed in commit f1de55ff7c70 ("dmaengine: ipu: Remove the driver")
in 2023-08
drivers/media/platform/soc_camera/mx3_camera.c
--> removed in commit c93cc61475eb ("[media] staging/media: remove
deprecated mx3 driver") in 2016-06
drivers/video/mx3fb.c
--> removed in commit bfac19e239a7 ("fbdev: mx3fb: Remove the driver")
in 2023-08
Now include/linux/dma/ipu-dma.h is unused and can be removed as-well.
