crypto: ccp - fix memleak in ccp_init_dm_workarea
[ Upstream commit a1c95dd5bc1d6a5d7a75a376c2107421b7d6240d ]
When dma_map_single() fails, wa->address is supposed to be freed
by the callers of ccp_init_dm_workarea() through ccp_dm_free().
However, many of the call spots don't expect to have to call
ccp_dm_free() on failure of ccp_init_dm_workarea(), which may
lead to a memleak. Let's free wa->address in ccp_init_dm_workarea()
when dma_map_single() fails.
