misc: hpilo: avoid a useless memset
Avoid a memset after a call to 'dma_alloc_coherent()'. This is useless since commit 518a2f1925c3 ("dma-mapping: zero memory returned from dma_alloc_*") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://lore.kernel.org/r/20200718070246.338016-1-christophe.jaillet@wanadoo.fr Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
