From 92ca0dc5ee022e4c0e488177e1d8865a0778c6c2 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 21 Oct 2010 10:49:10 +0200 Subject: [PATCH] USB: mct_u232: fix broken close Fix regression introduced by commit f26788da3b342099d2b02d99ba1cb7f154d6ef7b (USB: serial: refactor generic close) which broke driver close(). This driver uses non-standard semantics for the read urb which makes the generic close function fail to kill it (the read urb is actually an interrupt urb and therefore bulk_in size is zero).
