Subject: [PATCH V3 2/2] staging/comedi/drivers: free allocated priv and release resources if comedi_alloc_subdevices
Date: Sun, 1 Jul 2012 21:50:24 +0530 [thread overview]
Message-ID: <1341159624-23968-1-git-send-email-devendra.aaru@gmail.com> (raw)
as comedi_alloc_subdevices may fail, we leak out the memory allocated by alloc_private,
and also the I/O regions we requested.
free out the private data pointer of the driver, and release the I/O regions
