Subject: [PATCH] drm/nouveau/bo: mark expected switch fall-through
Date: Mon, 11 Feb 2019 12:58:35 -0600 [thread overview]
Message-ID: <20190211185835.GA19174@embeddedor> (raw)
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/gpu/drm/nouveau/nouveau_bo.c: In function ‘nouveau_ttm_io_mem_reserve’:
drivers/gpu/drm/nouveau/nouveau_bo.c:1434:53: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (drm->client.mem->oclass < NVIF_CLASS_MEM_NV50 || !mem->kind)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~
drivers/gpu/drm/nouveau/nouveau_bo.c:1438:2: note: here
case TTM_PL_VRAM:
^~~~
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.
