[PATCH libdrm 1/9] amdgpu: Pass file descriptor directly to amdgpu_close_kms_handle

Michel Dänzer michel at daenzer.net
Mon Jun 24 16:53:58 UTC 2019


From: Michel Dänzer <michel.daenzer at amd.com>

And propagate drmIoctl's return value.

This allows replacing all remaining open-coded DRM_IOCTL_GEM_CLOSE
ioctl calls with amdgpu_close_kms_handle calls.
