From c1ce7f10543d616920a1eb772b993c7d7815d653 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 26 Nov 2013 16:42:09 -0700 Subject: [PATCH] staging: comedi: mpc624: remove unnecessary test It's not necessaary to vaidate insn->n passed to the (*insn_read) function. The for() loop following it will just be a NOP. Remove the test as well as the printk noise.
