Yogendra Charya Tangalapally 84d4c5a179 ANDROID: sound: rawmidi: Hold lock around realloc 
The SNDRV_RAWMIDI_STREAM_{OUTPUT,INPUT} ioctls may reallocate
runtime->buffer while other kernel threads are accessing it.  If the
underlying krealloc() call frees the original buffer, then this can turn
into a use-after-free.
Most of these accesses happen while the thread is holding runtime->lock,
and can be fixed by just holding the same lock while replacing
runtime->buffer, however we can't hold this spinlock while
snd_rawmidi_kernel_{read1,write1} are copying to/from userspace.  We
need to add and acquire a new mutex to prevent this from happening
concurrently with reallocation.  We hold this mutex during the entire
reallocation process, to also prevent multiple concurrent reallocations
leading to a double-free.
