From eda6e6f86b5f95b982ac7ebf7cf5be2a29a291e9 Mon Sep 17 00:00:00 2001 From: Graf Yang Date: Sat, 22 May 2010 22:00:10 +0000 Subject: [PATCH] net/irda: bfin_sir: IRDA is not affected by anomaly 05000230 Anomaly 05000230 (over sampling of the UART STOP bit) applies only when the peripheral is operating in UART mode. So drop the anomaly handling in the IRDA code. Signed-off-by: Graf Yang Signed-off-by: Mike Frysinger Signed-off-by: David S.
