From f9721ed2707661af75a414d09cdcd71f99a13f62 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Sun, 29 Jan 2012 21:34:04 +0100 Subject: bcma: Fix mem leak in bcma_bus_scan() bcma_bus_scan() leaks 'struct bcma_device' bytes if bcma_get_next_core() returns error. Restructure the code so we always kfree() the memory we allocate to the variable 'core' before it goes out of scope. Signed-off-by: Jesper Juhl Signed-off-by: John W.
