Subject: [PATCH 5.2 002/135] sh: kernel: hw_breakpoint: Fix missing break in switch statement

From: "Gustavo A. R. Silva" <gustavo@...eddedor.com>

commit 1ee1119d184bb06af921b48c3021d921bbd85bac upstream.

Add missing break statement in order to prevent the code from falling
through to case SH_BREAKPOINT_WRITE.

Fixes: 09a072947791 ("sh: hw-breakpoints: Add preliminary support for SH-4A UBC.")
