The function ttm_bo_put releases a reference to a TTM buffer object. The function's name is more aligned to the Linux kernel convention of naming ref-counting function _get and _put. A call to ttm_bo_unref takes the address of the TTM BO object's pointer and clears the pointer's value to NULL. This is not necessary in most cases and sometimes even worked around by the calling code. A call to ttm_bo_put only releases the reference without clearing the pointer. The current behaviour of cleaning the pointer is kept in the calling code, but should be removed if not required in a later patch. Signed-off-by:

Currently the driver overwrites the surface depth provided by the fb helper to give an invalid bpp/surface depth combination. This has been exposed by commit 70109354 ("drm: Reject unknown legacy bpp and depth for drm_mode_addfb ioctl"), which now causes the driver to fail to probe. Fix by not overwriting the surface depth.

In hibmc_drm_fb_create(), when the call to hibmc_framebuffer_init() fails with error, do not store the error code in the HiBMC device frame-buffer pointer, as this will be later checked for non-zero value in hibmc_fbdev_destroy() when our intention is to check for a valid function pointer.

The N value was computed by kernel driver that based on synchronous clock mode. But only specific N value (0x8000) would be acceptable for LG LP140WF6-SPM1 eDP panel which is running at asynchronous clock mode.
