From 9fe041f6fdfedd92e15dd81d96475ff04bdf879e Mon Sep 17 00:00:00 2001 From: Jordan Crouse Date: Wed, 7 Nov 2018 15:35:50 -0700 Subject: drm/msm: Add msm_gem_get_and_pin_iova() Add a new function to get and pin the iova memory in one step (basically renaming the old msm_gem_get_iova function) and switch msm_gem_get_iova() to only allocate an iova but not map it in the IOMMU. This is only currently used by msm_ioctl_gem_info() since all other users of of the iova expect that the memory be immediately available.
