From 91f189de4640a6531a00fbc6a6c6adc7804af1e9 Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Thu, 16 Oct 2014 14:19:48 -0400 Subject: [PATCH] serial: Fix sparse warnings in uart_throttle()/uart_unthrottle() The struct uart_port.flags field is type upf_t, as are the matching bit definitions. Change local mask variable to type upf_t.
