From 305a6f3896350bbfa59c0021f59600bbbb2e9590 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Thu, 10 Jan 2013 10:36:58 -0700 Subject: [PATCH] staging: comedi: comedi_buf: remove BUG_ON in comedi_buf_munge() The condition that would trigger this BUG_ON can never occur. The 'munge_count' will be equal to 'buf_write_count' if all the data in the buffer has been munged. Or, the 'munge_count' will be less than the 'buf_write_count' if any partial samples in the buffer were not munged. The 'munge_count' will never be greater than the 'buf_write_count'. Remove the unnecessary BUG_ON.
