Subject: [PATCH v2 1/7] allwinner-a10-pit: Use ptimer_free() in the finalize function to avoid memleaks
Date: Thu, 17 Dec 2020 19:31:48 +0800 [thread overview]
Message-ID: <20201217113154.121668-1-ganqixin@huawei.com> (raw)
When running device-introspect-test, a memory leak occurred in the a10_pit_init
function, so use ptimer_free() in the finalize function to avoid it.
ASAN shows memory leak stack:
Indirect leak of 288 byte(s) in 6 object(s) allocated from:
#0 0xffffab97e1f0 in __interceptor_calloc (/lib64/libasan.so.5+0xee1f0)
#1 0xffffab256800 in g_malloc0 (/lib64/libglib-2.0.so.0+0x56800)
