From 4db1f47c29bd19e2069fb877620540db2a51a572 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Fri, 24 Oct 2014 15:33:53 -0700 Subject: [PATCH] Input: vsxxxaa - fix code dropping bytes from queue I believe the intent of the code was to drop oldest bytes from the queue, not the latest if we drop one byte and both latest and some oldest of we are dropping more than one.
