Hi all,

After merging the kspp-gustavo tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

/home/sfr/next/next/drivers/gpu/drm/msm/msm_gem.c: In function 'msm_gem_new_impl':
/home/sfr/next/next/drivers/gpu/drm/msm/msm_gem.c:1170:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
1170 | if (priv->has_cached_coherent)
| ^
/home/sfr/next/next/drivers/gpu/drm/msm/msm_gem.c:1173:2: note: here
1173 | default:
| ^~~~~~~

Introduced by commit

d12e339044a0 ("drm/msm: add MSM_BO_CACHED_COHERENT")

Presumably exposed by commit

73ffc61f4a8b ("Makefile: Enable -Wimplicit-fallthrough for Clang")

though I am not sure why since I am building with gcc. The first
commit above introduces a new use of /* fallthrough */
