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.

In particular, the current code bails out on odd CRC errors in recent Macbooks. This patch ignores those errors, with the argument that an unrecognized SPROM should be treated similarly to a non-existing one. Signed-off-by: Henrik Rydberg Signed-off-by: John W.
