Subject[PATCH] scsi: qla2xxx: Fix the size used in a 'dma_free_coherent()' call
Date
Update the size used in 'dma_free_coherent()' in order to match the one
used in the corresponding 'dma_alloc_coherent()'.

While at it, remove a memset after a call to 'dma_alloc_coherent()'.
This is useless since
commit 518a2f1925c3 ("dma-mapping: zero memory returned from dma_alloc_*")

Fixes: 4161cee52df8 ("[SCSI] qla4xxx: Add host statistics support")
Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
---
The memset has been added in the same commit, so I think it is ok to
remove it in the same path.
