From f1e949ac4ea1f4e37187949944899afeaff33e1e Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Wed, 17 Mar 2010 23:05:59 +0100 Subject: [PATCH] USB: serial: export generic throttle and unthrottle Allow drivers to use the generic throttle and unthrottle implementation. This makes sense for drivers using the generic read functionality. Note that drivers need to set these explicitly in order to enable them (i.e., we do not set them at port probe if not defined).
