[Mesa-dev] [PATCH v2 2/6] loader: use drmGetDevice[s]2 API

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

By this allows us to fetch the device list/info w/o the revision field.
At the moment retrieving the latter wakes up the device.

Note: kernel patch to resolve that should be in 4.10.

Due to a libtool bug^Wfeature one can get link time errors if libdrm is
in a non-default prefix. To workaround set LD_LIBRARY_PATH before your
mesa `make install'.

^^ was seemingly hit on the Intel CI. Will need to check with Mark as
he gets up.
