[PATCH] drm/imx: imx-ldb: Remove the leftover LVDS_BIT_MAP_SPWG/JEIDA enums

[PATCH] drm/imx: imx-ldb: Remove the leftover LVDS_BIT_MAP_SPWG/JEIDA enums

[Liu Ying]

No one is using the LVDS_BIT_MAP_SPWG/JEIDA enums since a previous
commit which changes the imx_ldb_bit_mappings[] array definition,
so let's remove them.

Fixes: 5e501ed7253b ("drm/imx: imx-ldb: allow to determine bus format from the connected panel")

Hi Liu,

pls check [1], I already send patches for it. Those stuck because we
need to verify Philipp's proposal.

Hi Macro,

Yeah, '[PATCH 09/17] drm/imx: imx-ldb: remove useless enum' in your
patch series does the same thing as this patch does.  I'm fine to drop
this patch then.

Regarding Philipp's proposal on the use-after-free issue, we've got the
basically the same implemetation in downstream ldb driver to address
the issue.

Liu Ying
