Hello Hersen Wu, The patch cb1d7eacb58f: "drm/amd/display: Fix indentation in dcn10 resource constructor" from May 8, 2018, leads to the following static checker warning: drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_resource.c:1008 construct() warn: inconsistent indenting drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_resource.c 996 static bool construct( 997 uint8_t num_virtual_links, 998 struct dc *dc, 999 struct dcn10_resource_pool *pool) 1000 { 1001 int i; 1002 int j; 1003 struct dc_context *ctx = dc->ctx; 1004 uint32_t pipe_fuses = read_pipe_fuses(ctx); 1005 1006 ctx->dc_bios->regs = &bios_regs; 1007 1008 pool->base.res_cap = &res_cap; ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This line was indented correctly in the original code when it was merged last November... It's a mystery. Merge error perhaps? https://www.mail-archive.com/amd-gfx at lists.freedesktop.org/msg21750.html 1009 1010 pool->base.funcs = &dcn10_res_pool_funcs; 1011 1012 /* 1013 * TODO fill in from actual raven resource when we create 1014 * more than virtual encoder 1015 */ regards, dan carpenter
