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()2017-07-04T10:11:17+00:00Murray McAllistermurray.mcallister@insomniasec.com2017-03-27T09:15:12+00:00urn:sha1:b2b98051a7d8b2ba71924ce7f488c9c559b91722
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.
