Subject[PATCH 4.18 212/235] selftests/android: initialize heap_type to avoid compiling warning
Date
4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Li Zhijian <lizhijian@cn.fujitsu.com>

[ Upstream commit cc7c673032fc7427087e74b75f732b43db38a256 ]

Initialize heap_type to ION_HEAP_TYPE_SYSTEM to avoid "used uninitialized"
compiler warning. heap_type gets used after initialization, this change is
to just keep the compiler happy.

make[1]: warning: jobserver unavailable: using -j1. Add '+' to parent make rule.
