This array has a fixed size\nand the index was not being checked against the array's bounds before\naccessing it.\n\nThis fix adds a conditional check to ensure that the hpd_source index is\nwithin the valid range of the link_enc_hpd_regs array. If the index is\nout of bounds, the function now returns NULL to prevent undefined\nbehavior.\n\nReferences:\n\n[ 65.920507] ------------[ cut here ]------------\n[ 65.920510] UBSAN: array-index-out-of-bounds in drivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn21/dcn21_resource.c:1312:29\n[ 65.920519] index 7 is out of range for type 'dcn10_link_enc_hpd_registers [5]'\n[ 65.920523] CPU: 3 PID: 1178 Comm: modprobe Tainted: G OE 6.8.0-cleanershaderfeatureresetasdntipmi200nv2132 #13\n[ 65.920525] Hardware name: AMD Majolica-RN/Majolica-RN, BIOS WMJ0429N_Weekly_20_04_2 04/29/2020\n[ 65.920527] Call Trace:\n[ 65.920529] \n[ 65.920532] dump_stack_lvl+0x48/0x70\n[ 65.920541] dump_stack+0x10/0x20\n[ 65.920543] __ubsan_handle_out_of_bounds+0xa2/0xe0\n[ 65.920549] dcn21_link_encoder_create+0xd9/0x140 [amdgpu]\n[ 65.921009] link_create+0x6d3/0xed0 [amdgpu]\n[ 65.921355] create_links+0x18a/0x4e0 [amdgpu]\n[ 65.921679] dc_create+0x360/0x720 [amdgpu]\n[ 65.921999] ?
