[PATCH] drm/msm/mdp5: Remove set but not used variable 'hw_cfg' in modeset_init

[PATCH] drm/msm/mdp5: Remove set but not used variable 'hw_cfg' in modeset_init

[zhengbin]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c: In function modeset_init:
drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c:458:28: warning: variable hw_cfg set but not used [-Wunused-but-set-variable]

It is not used since commit 36d1364abbed ("drm/msm/mdp5:
Clean up interface assignment")
