From: Gustavo A. R. Silva Date: Fri, 15 Feb 2019 17:05:46 +0000 (-0600) Subject: drm/drm_vm: Mark expected switch fall-throughs X-Git-Tag: Ubuntu-5.13.0-19.19~8591^2~36^2~89 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=58db702266c16b8df29115ec919d56c820545d8c;p=mirror_ubuntu-jammy-kernel.git drm/drm_vm: Mark expected switch fall-throughs In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by: Gustavo A. R.
