[PATCH] crypto: cavium: fix dma_free_coherent() size

Posted by Thomas Fourier 1 month, 3 weeks ago

The size of the buffer in alloc_command_queues() is
curr->size + CPT_NEXT_CHUNK_PTR_SIZE, so used that length for
dma_free_coherent().

Fixes: c694b233295b ("crypto: cavium - Add the Virtual Function driver for CPT")
