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

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.

Regards
Tony P
