From 61698b7e222c33e1d38996519b38dd34cbcb8634 Mon Sep 17 00:00:00 2001 From: Christian Engelmayer Date: Thu, 10 Apr 2014 20:37:53 +0200 Subject: [PATCH] rsi: Fix a potential memory leak in rsi_send_auto_rate_request() Fix a potential memory leak in the error path of function rsi_send_auto_rate_request(). In case memory allocation for array 'selected_rates' fails, the error path exits and leaves the previously allocated skb in place. Detected by Coverity: CID 1195575.
