X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2dad9d4d057a080a4ad59c705b3e388af6794576;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git i915: add stub dma-buf mmap callback. This just adds a stub for now, until we have some users in place to test this functionality properly.
