From b2e1be03ac1747cbb758fa146fe5cf364f306420 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 25 Jan 2013 18:37:06 -0700 Subject: [PATCH] staging: comedi: ni_labpc_cs: remove pcmcia_device private data The private data, struct local_info_t, is not being used in the driver. Remove it as well as the kzalloc/kfree. Also, don't set the 'pcmcia_cur_dev' variable unless the pcmcia configuration is successful.
