6.13-stable review patch. If anyone has any objections, please let me know. ------------------ From: Alex Hung <alex.hung@xxxxxxx> commit 79e31396fdd7037c503e6add15af7cb00633ea92 upstream. [WHY & HOW] A warning message "WARNING: CPU: 4 PID: 459 at ... /dc_resource.c:3397 calculate_phy_pix_clks+0xef/0x100 [amdgpu]" occurs because the display_color_depth == COLOR_DEPTH_141414 is not handled. This is observed in Radeon RX 6600 XT. It is fixed by assigning pix_clk * (14 * 3) / 24 - same as the rests. Also fixes the indentation in get_norm_pix_clk.
