Subject: [PATCH v2] drm/hisilicon: Delete the entire file hibmc_ttm.c
Date:   Fri, 4 Dec 2020 09:23:18 +0800
Message-ID: <1607044999-47666-13-git-send-email-tiantao6@hisilicon.com>

Precedence: bulk

Delete the entire file hibmc_ttm.c. drmm_vram_helper_init() can be
called directly from hibmc_load(). hibmc_dumb_create() and
hibmc_mode_funcs can go to hibmc_drm_drv.c

v2:
change Deletted to Delete
