From db652e4b36e5f1e5f49a4a49caf3aa365fe851c4 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Sun, 6 Nov 2011 22:58:31 +0100 Subject: [PATCH] net, wireless, mwifiex: Fix mem leak in mwifiex_update_curr_bss_params() If kmemdup() fails we leak the memory allocated to bss_desc. This patch fixes the leak. I also removed the pointless default assignment of 'NULL' to 'bss_desc' while I was there anyway. Signed-off-by: Jesper Juhl Reviewed-by: Srivatsa S.
