Since commit 987d65d0 (drm: debugfs: make drm_debugfs_create_files() never fail), drm_debugfs_create_files() never fails and should return void. Therefore, remove its use as the return value of hdlcd_debugfs_init() and have the latter function return 0 directly. v2: make hdlcd_debugfs_init() return 0 instead of void to ensure that each patch compiles individually.

Andrzej Pietrasiewicz authored
Allow allocating a specialized version of struct drm_framebuffer by moving the actual fb allocation out of drm_gem_fb_create_with_funcs(); the respective functions names are adjusted to reflect that fact. Please note, though, that standard size checks are performed on buffers, so the drm_gem_fb_init_with_funcs() is useful for cases where those standard size checks are appropriate or at least don't conflict the checks to be performed in the specialized case. Thanks to this change the drivers can call drm_gem_fb_init_with_funcs() having allocated their special version of struct drm_framebuffer, exactly the way the new version of drm_gem_fb_create_with_funcs() does.

Variables declared in a switch statement before any case statements cannot be automatically initialized with compiler instrumentation (as they are not part of any execution flow). With GCC's proposed automatic stack variable initialization feature, this triggers a warning (and they don't get initialized). Clang's automatic stack variable initialization (via CONFIG_INIT_STACK_ALL=y) doesn't throw a warning, but it also doesn't initialize such variables[1]. Note that these warnings (or silent skipping) happen before the dead-store elimination optimization phase, so even when the automatic initializations are later elided in favor of direct initializations, the warnings remain. To avoid these problems, lift such variables up into the next code block. drivers/gpu/drm/drm_edid.c: In function ‘drm_edid_to_eld’: drivers/gpu/drm/drm_edid.c:4395:9: warning: statement will never be executed [-Wswitch-unreachable] 4395 | int sad_count; | ^~~~~~~~~ [1] https://bugs.llvm.org/show_bug.cgi?id=44916 v2: move into function block instead being switch-local (Ville Syrjälä) Signed-off-by:Kees Cook <keescook@chromium.org> [danvet: keep the changelog] Signed-off-by:
