From a6b93a908508810c5d51dd9b390283345af6f2d9 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 1 Oct 2006 17:17:40 +0100 Subject: [SERIAL] Fix oops when removing suspended serial port A serial card might have been removed when the system is resumed. This results in a suspended port being shut down, which results in the ports shutdown method being called twice in a row. This causes BUGs. Avoid this by tracking the suspended state separately from the initialised state.
