[PATCH] drm/amd/display: Remove duplicate code across dcn30 and dcn31
From: Maíra Canal
Date: Thu Jun 30 2022 - 16:18:10 EST
The function CalculateBytePerPixelAnd256BBlockSizes was defined four
times: on display_mode_vba_30.c, display_rq_dlg_calc_30.c,
display_mode_vba_31.c and display_rq_dlg_calc_31.c. In order to avoid
code duplication, the CalculateBytePerPixelAnd256BBlockSizes is defined
on display_mode_vba_30.h and used across dcn30 and dcn31.
