drm/amd/display: fix dereference before NULL check

2021-12-30T13:54:45Z

The "plane_state" pointer was access before checking if it was NULL. Avoid a possible NULL pointer dereference by accessing the plane address after the check.

drm/amd/display: fix function scopes

2021-12-13T21:34:26Z

This turns previously global functions into static, thus removing compile-time warnings such as: warning: no previous prototype for 'get_highest_allowed_voltage_level' [-Wmissing-prototypes] 742 | unsigned int get_highest_allowed_voltage_level(uint32_t chip_family, uint32_t hw_internal_rev, uint32_t pci_revision_id) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ warning: no previous prototype for 'rv1_vbios_smu_send_msg_with_param' [-Wmissing-prototypes] 102 | int rv1_vbios_smu_send_msg_with_param(struct clk_mgr_internal *clk_mgr, unsigned int msg_id, unsigned int param) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Changes since v1: - As suggested by Rodrigo Siqueira: 1. Rewrite function signatures to make them more readable. 2. Get rid of unused functions in order to remove 'defined but not used' warnings.
