# commit 88c5083442454e5e8a505b11fa16f32d2879651e
# Merge: 43e317c1bbdf a035d552a93b
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Sat Jul 27 11:04:18 2019 -0700

#     Merge tag 'Wimplicit-fallthrough-5.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux
#     
#     Pull Wimplicit-fallthrough enablement from Gustavo A. R. Silva:
#      "This marks switch cases where we are expecting to fall through, and
#       globally enables the -Wimplicit-fallthrough option in the main
#       Makefile.
#     
#       Finally, some missing-break fixes that have been tagged for -stable:
#     
#        - drm/amdkfd: Fix missing break in switch statement
#     
#        - drm/amdgpu/gfx10: Fix missing break in switch statement
#     
#       With these changes, we completely get rid of all the fall-through
#       warnings in the kernel"
