[PATCH v2 6/9] staging: android: ion: Remove dead code in ion_page_pool_free

From: Yisheng Xie
Date: Mon Feb 12 2018 - 05:52:48 EST


ion_page_pool_add will always return 0, however ion_page_pool_free will
call ion_page_pool_free_pages when ion_page_pool_add's return value is
not 0, so it is a dead code which can be removed.
