Alex HungandGreg Kroah-Hartman 72c9c01c57 drm/amd/display: Validate hw_points_num before using it ...

[ Upstream commit 58c3b3341c ]

[WHAT]
hw_points_num is 0 before ogam LUT is programmed; however, function
"dwb3_program_ogam_pwl" assumes hw_points_num is always greater than 0,
i.e. substracting it by 1 as an array index.

[HOW]
Check hw_points_num is not equal to 0 before using it.
