Wimplicit-fallthrough patches for 5.3-rc5 

Hi Linus,
 
 Please, pull the following patches that fix sh mainline builds:
 
  - Fix fall-through warning in sh.
  - Fix missing break bug in sh (this is a 10-year-old bug).
 
 Currently, mainline builds for sh are broken. These patches fix that.
 
 Thanks
