From: H Hartley Sweeten Date: Mon, 25 Jun 2012 23:20:36 +0000 (-0700) Subject: staging: comedi: cb_das16_cs: remove unused pcmcia 'stop' logic X-Git-Tag: next-20120724~21^2~538 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c8b2ae2b98bad7870ec6be24e517bacffd76ea8e;p=karo-tx-linux.git staging: comedi: cb_das16_cs: remove unused pcmcia 'stop' logic The pcmcia support code in this driver appears to be cut-and- paste from some other driver. It has code in it to stop the device during suspend but nothing in the main comedi_driver uses it. Remove the 'stop' variable from the pcmcia private data and all the logic that deals with it.
