* drm/vmwgfx: Remove getparam error messageThomas Hellstrom2017-07-041-2/+0
| | | | | | | | | | | | | | commit 53e16798b0864464c5444a204e1bb93ae246c429 upstream. The mesa winsys sometimes uses unimplemented parameter requests to check for features. Remove the error message to avoid bloating the kernel log.

* drm/vmwgfx: avoid calling vzalloc with a 0 size in vmw_get_cap_3d_ioctl()Murray McAllister2017-07-041-1/+1
| | | | | | | | | | | | | | | commit 63774069d9527a1aeaa4aa20e929ef5e8e9ecc38 upstream. In vmw_get_cap_3d_ioctl(), a user can supply 0 for a size that is used in vzalloc(). This eventually calls dump_stack() (in warn_alloc()), which can leak useful addresses to dmesg. Add check to avoid a size of 0.
