[PATCH 06/87] ata:sata_qstor: Remove call to memset after dmam_alloc_coherent

From: Fuqian Huang
Date: Thu Jun 27 2019 - 13:34:36 EST


In commit af7ddd8a627c
("Merge tag 'dma-mapping-4.21' of git://git.infradead.org/users/hch/dma-mapping"),
dmam_alloc_coherent has already zeroed the memory.
So memset is not needed.
