2022-07-30	lib: utils/serial: Ensure baudrate is non-zero before using	Andrew Jones	1	-1/+1
	RISC-V doesn't generate exceptions on divide-by-zero, but the result, all bits set, is not likely what people expect either. In all cases where we divide by baudrate there's a chance it's zero (when the DT it came from is "bad"). To avoid difficult to debug situations, leave baudrate dependent registers alone when baudrate is zero, as, also in all cases, it appears we can skip initialization of those registers and still [hopefully] have a functioning UART.

2022-01-21	lib: fix pointer of type 'void *' used in arithmetic	Jukka Laitinen	1	-2/+2
	Using "void " in arithmetic causes errors with strict compiler settings: "error: pointer of type 'void ' used in arithmetic [-Werror=pointer-arith]" Avoid these by calculating on "char *" where 1-byte data size is assumed.
