Bug: Cube MX PLL configuration

After generating the code using cube MX version 4.22.1 for STM32L476VG board, I noticed that RCC_OscInitStruct.PLL.PLLM does not get assigned to any value in SystemClock_Config().

Due to this RCC_PLLCFGR register enables unwanted PLLs.

For eg in my case I was expecting only PLLR to be enabled with register value to be 0x1002a71 but it turned out to be RCC_PLLCFGR = 0x7737f71 where PLLQ and PLLP is also eanabled.

As any one else noticed this issue?
