From cf2c7481d2ff7f0c266de873b2fe93883e9782f9 Mon Sep 17 00:00:00 2001 From: Pete Zaitcev Date: Mon, 22 May 2006 21:58:49 -0700 Subject: [PATCH] USB serial: encapsulate schedule_work, remove double-calling I'm going to throw schedule_work away, it's retarded. But for starters, let's have it encapsulated. Also, generic and whiteheat were both calling usb_serial_port_softint and scheduled work. Only one was necessary.
