Subject: crypto/mrvl: print message if DMA mem is initialized
X-Git-Tag: spdx-start~1205
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5f4a38008da5861cbb4a2cc5718c7d4401cc9452;p=dpdk.git

crypto/mrvl: print message if DMA mem is initialized

In case MUSDK dma memory has been already initialized by a different
driver (and perhaps do the different size) mv_sys_dma_mem_init()
will return -EEXIST error code.

Printing extra message makes it clear.
