FW: [PATCH] drm/amd/display: check for ipp before calling cursor operations

[S, Shirish]

From: Shirish S <shirish.s at amd.com>

Currently all cursor related functions are made to all pipes that are attached to a particular stream.
This is not applicable to pipes that do not have cursor plane initialised like underlay.
Hence this patch allows cursor related operations on a pipe only if ipp in available on that particular pipe.

The check is added to set_cursor_position & set_cursor_attribute.
