[igt-dev] [PATCH i-g-t v1 0/3] Add helper method to get primary plane assigned by driver

[Jessica Zhang]

This patch series introduces a helper method to get the primary plane
assigned to a pipe by the driver.

Currently, IGT will use igt_pipe_get_plane_type to get the primary
plane of a pipe and assumes that this is also the plane being assigned
to the pipe by the driver. This isn't necessarily true in cases where
there are multiple primary planes and causes a mismatch between IGT
and driver.

To address this issue, this patch series introduces a helper method to
get the primary plane being assigned to a pipe by the driver and adds
calls to the method within some KMS subtests.
