net: ipa: kill the allocated transaction list
The only place the trans_info->alloc list is used is when initializing it, when adding a transaction to it when allocation finishes, and when moving a transaction from that list to the committed list. We can just skip putting a transaction on the allocated list, and add it (rather than move it) to the committed list when it is committed. On additional caveat is that an allocated transaction that's committed without any TREs added will be immediately freed. Because we aren't adding allocated transactions to a list any more, the list links need to be initialized to ensure they're valid at the time list_del() is called for the transaction. Then we can safely eliminate the allocated transaction list. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
