2019-08-16ALSA: firewire: fix a memory leak bugWenwen Wang1-1/+1
commit 1be3c1fae6c1e1f5bb982b255d2034034454527a upstream. In iso_packets_buffer_init(), 'b->packets' is allocated through kmalloc_array(). Then, the aligned packet size is checked. If it is larger than PAGE_SIZE, -EINVAL will be returned to indicate the error. However, the allocated 'b->packets' is not deallocated on this path, leading to a memory leak. To fix the above issue, free 'b->packets' before returning the error code.

2011-11-01sound: Add export.h for THIS_MODULE/EXPORT_SYMBOL where neededPaul Gortmaker1-0/+1
These aren't modules, but they do make use of these macros, so they will need export.h to get that definition. Previously, they got it via the implicit module.h inclusion. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
