[PATCH AUTOSEL 5.15 07/10] drm/amd/display: Reduce number of arguments of dml31's CalculateWatermarksAndDRAMSpeedChangeSupport()

From: Nathan Chancellor nathan@kernel.org

[ Upstream commit 37934d4118e22bceb80141804391975078f31734 ]

Most of the arguments are identical between the two call sites and they can be accessed through the 'struct vba_vars_st' pointer. This reduces the total amount of stack space that dml31_ModeSupportAndSystemConfigurationFull() uses by 240 bytes with LLVM 16 (2216 -> 1976), helping clear up the following clang warning:

drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn31/display_mode_vba_31.c:3908:6: error: stack frame size (2216) exceeds limit (2048) in 'dml31_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than] void dml31_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib) ^ 1 error generated.
