X-Git-Tag: v5.11-rc1~177^2~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e689b300c99ca2dd80d3f662e19499bba27cda09;p=thirdparty%2Fkernel%2Flinux.git

kprobes/x86: Fix fall-through warnings for Clang

In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning
by explicitly adding a break statement instead of just letting the code
fall through to the next case.
