[PATCH] clk: vt8500: Missing breaks in vtwm_pll_round_rate/_set_rate.

[PATCH] clk: vt8500: Missing breaks in vtwm_pll_round_rate/_set_rate.

[Tony Prisk]

The case of PLL_TYPE_WM8750 in both these functions is missing a break
statement causing a fall-through to the default: case.

Insert the missing break statements.

Mike,

Any chance this can still go in as a fix for 3.9
The fault makes it impossible to set the PLL clocks on WM8750 and later SoCs.

[PATCH] ARM: KVM: Add missing break;

[Joe Perches]

commit 3401d54696f ("KVM: ARM: Introduce KVM_ARM_SET_DEVICE_ADDR ioctl")
added the case, but omitted adding break;

Add it.

Found with grep version 2.54 pattern:

$ grep -rP --include=*.[ch] "\b(\w+)\s*=[^;]+;\s*(?:case\s+\w+:|default:)\s*\1\s*="
