From 97641816b58fccaf157ab5093f55f0a319d7a55f Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Thu, 1 Nov 2012 17:30:37 -0700 Subject: [PATCH] staging: comedi: addi_apci_3120: cleanup apci3120_detach() This driver always tried to allocate the dma buffers so they need to be free'd when the board is detached. Remove the unneeded tests for the eeprom chip and bring the code back an indent.
