[PATCH] imx-drm: imx-drm-core: Convert to drm_is_master()

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at freescale.com>

Since commit fe32c9f34b9e ("drm: drop redundant drm_file->is_master")
we should use drm_is_master, otherwise the following build error is seen:

drivers/staging/imx-drm/imx-drm-core.c: In function 'imx_drm_driver_preclose':
drivers/staging/imx-drm/imx-drm-core.c:185:11: error: 'struct drm_file' has no member named 'is_master'

Reported-by: kbuild test robot <fengguang.wu at intel.com>

This one should go via David Herrmann's tree.
