[PATCH] drm: msm: remove unused variable

[PATCH] drm: msm: remove unused variable

[Arnd Bergmann]

A recent cleanup removed the only user of the 'kms' variable in
msm_preclose(), causing a harmless compiler warning:

drivers/gpu/drm/msm/msm_drv.c: In function 'msm_preclose':
drivers/gpu/drm/msm/msm_drv.c:468:18: error: unused variable 'kms' [-Werror=unused-variable]

This removes the variable as well.

I just realized that this is now the only defconfig warning we get in v4.6 with
a recent compiler. Any chance we can still squeeze this in the current release?

I don't have anything else to send for -fixes at the moment, but

Dave, if you are sending another -fixes, mind grabbing this:

  git pw apply -s 5827

(or if you are still on the old pw, 'pwclient git-am 8277241')
