From: Anirudha Sarangi <redacted> The existing implementation includes overrun errors under IGNPAR option. This patch fixes it by including only parity and framing error under IGNPAR option.
The convention adopted by Linux serial drivers is to ignore overrun errors if both IGNPAR and IGNBRK are set. Regards, Peter Hurley
