Subject: [PATCH] orinoco: Fix walking past the end of the buffer
Date: Wed, 11 Aug 2010 20:32:16 +0000 [thread overview]
Message-ID: <20100811203216.GA25168@hera.kernel.org> (raw)
Fix walking past the end of the bitrate_table array
in the case when the loop counter == BITRATE_TABLE_SIZE.
Mark bitrate as invalid in this case for the orinoco_ioctl_setrate()
