Hi Greg,
below is the manual backport of an upstream patch to fix the build failure in kernel v4.14 in imsttfb.c.
It's not sufficient to just return from init_imstt() as the kernel then may crash later when it tries to access the non-existent framebuffer or cmap. Instead return failure to imsttfb_probe() so that the kernel will skip using that hardware/driver.
Can you please apply this patch to the v4.14 stable queue?
Now queued up, thanks!
