[PATCH v3 21/27] tty: remove unneeded memset

From: Fuqian Huang
Date: Tue Jul 02 2019 - 03:59:36 EST


pci_alloc_consistent calls dma_alloc_coherent directly.
In commit 518a2f1925c3
("dma-mapping: zero memory returned from dma_alloc_*"),
dma_alloc_coherent has already zeroed the memory.
So memset is not needed.
