[ Upstream commit 21915eca088dc271c970e8351290e83d938114ac ] build_initial_tok_table() overwrites unused sym_entry to shrink the table size. Before the entry is overwritten, table[i].sym must be freed since it is malloc'ed data. This fixes the 'definitely lost' report from valgrind. I ran valgrind against x86_64_defconfig of v5.4-rc8 kernel, and here is the summary: [Before the fix] LEAK SUMMARY: definitely lost: 53,184 bytes in 2,874 blocks [After the fix] LEAK SUMMARY: definitely lost: 0 bytes in 0 blocks Signed-off-by: NMasahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: NSasha Levin <sashal@kernel.org> Signed-off-by: NYang Yingliang <yangyingliang@huawei.com>7678eadc
