I have taken another look at this change idea.
Can the function call “devm_kfree(dev, imxpd)” become relevant
also at this place?
Would you like to combine it with the update suggestion
“Fix error handling for a kmemdup() call in imx_p
No, that is not correct! You should not try to free imxpd here as it
is a resource-managed allocation via devm_kzalloc(). It means memory
allocated with this function is automatically freed on driver detach.
So, this patch introduces a double-free.

In imx_pd_bind, the duplicated memory for imxpd->edid via kmemdup should
be released in drm_of_find_panel_or_bridge or imx_pd_register fail.
