[PATCH v2 02/19] media: omap3isp: allow it to build with COMPILE_TEST

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There aren't much things required for it to build with COMPILE_TEST.
It just needs to provide stub for an arm-dependent include.

Let's replicate the same solution used by ipmmu-vmsa, in order
to allow building omap3 with COMPILE_TEST.

The actual logic here came from this driver:

   drivers/iommu/ipmmu-vmsa.c
