[PATCH] staging: drm/imx: remove an unnecessary local variable

[Liu Ying]

This patch removes an unnecessary local variable defined
in the function imx_drm_driver_unload() so as to fix the
following build warning.

drivers/staging/imx-drm/imx-drm-core.c: \
In function ?imx_drm_driver_unload?:
drivers/staging/imx-drm/imx-drm-core.c:87:25: \
warning: unused variable ?imxdrm? [-Wunused-variable]

Already-Naked-by: me.  This is required by later patches in the series
posted earlier.

FTTC broadband for 0.8mile line: 5.8Mbps down 500kbps up.  Estimation
in database were 13.1 to 19Mbit for a good line, about 7.5+ for a bad.
Estimate before purchase was "up to 13.2Mbit".

Sorry. Did you mean that you have already got a fix for this?

No, I mean patches which come after the three which Greg has recently
merged - one of which removes users of the above variable - reintroduce
users of this variable, so deleting the variable will break those patches.
It was also pointless to remove it and then bring it back in the series.
