USB: serial: ch341: fix receiver regression

2020-02-10T09:10:35+00:00

While assumed not to make a difference, not using the factor-2 prescaler makes the receiver more susceptible to errors. Specifically, there have been reports of problems with devices that cannot generate a 115200 rate with a smaller error than 2.1% (e.g. 117647 bps). But this can also be reproduced with a low-speed RS232 tranceiver at 115200 when the input rate matches the nominal rate. So whenever possible, enable the factor-2 prescaler and halve the divisor in order to use settings closer to that of the previous algorithm.

USB: serial: ir-usb: Silence harmless uninitialized variable warning

2020-02-10T09:06:51+00:00

The "actual_length" variable might be uninitialized on some failure paths. It's harmless but static analysis tools like Smatch complain and at runtime the UBSan tool will likely complain as well.
