From 2284f47fe9fe2ed2ef619e5474e155cfeeebd569 Mon Sep 17 00:00:00 2001 From: Wang Wensheng Date: Thu, 29 Apr 2021 22:57:58 -0700 Subject: mm/sparse: add the missing sparse_buffer_fini() in error branch sparse_buffer_init() and sparse_buffer_fini() should appear in pair, or a WARN issue would be through the next time sparse_buffer_init() runs. Add the missing sparse_buffer_fini() in error branch.
