From c5f764057f2313673aaf046776e6d573bf2662b6 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 22 Mar 2016 11:21:35 -0700 Subject: [PATCH] staging: comedi: ni_labpc: remove some unnecessary defines The EEPROM_SIZE and NUM_AO_CHAN defines are only used once and they don't add any significant clarity to the driver. They are also pretty generic symbol names. Remove them and just open code the values.
