Subject: Staging: android: ion: duplicated clearing of sg_table
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b6152016003b2cc2370899558bf2e7de4ebd0b09;p=openwrt%2Fstaging%2Fblogic.git

Staging: android: ion: duplicated clearing of sg_table

Because sg_table is cleared in sg_alloc_table via memset we don't need to use
kzalloc to allocate sg_table.
