From 24692801a4d03dabb64e38b10d089beb3710be9d Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 29 Jan 2015 13:12:05 -0300 Subject: [PATCH] [media] davinci: add V4L2 dependencies The davinci media drivers use videobuf2, which they enable through a 'select' statement. If one of these drivers is built-in, but the v4l2 core is a loadable modules, we end up with a link error: drivers/built-in.o: In function `vb2_fop_mmap': :(.text+0x113e84): undefined reference to `video_devdata' drivers/built-in.o: In function `vb2_ioctl_create_bufs': :(.text+0x114710): undefined reference to `video_devdata' drivers/built-in.o: In function `vb2_ioctl_reqbufs': :(.text+0x114ed8): undefined reference to `video_devdata' drivers/built-in.o: In function `vb2_ioctl_querybuf': :(.text+0x115530): undefined reference to `video_devdata' To solve this, we need to add a dependency on VIDEO_V4L2, which enforces that the davinci drivers themselves can only be loadable modules if V4L2 is not built-in, and they do not cause the videobuf2 code to be built-in.
