From: H Hartley Sweeten Date: Mon, 20 Oct 2014 18:34:16 +0000 (-0700) Subject: staging: comedi: addi_apci_3120: rename private data 'i_IobaseAmcc' X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=323503bfec1a0e1a310ec8e483b528f5e4b87c2d;p=openwrt%2Fstaging%2Fblogic.git staging: comedi: addi_apci_3120: rename private data 'i_IobaseAmcc' This member of the private data holds the start address of PCI BAR 0 that is used to access the AMCC registers. Rename this CamelCase member and fix its type. Remove an unnecessary local variable, 'ui_Tmp', in apci3120_cyclic_ai() and tidy up the rest of the local variable declarations.
