Subject: [PATCH] ionic_lif: Use devm_kcalloc() in ionic_qcq_alloc()
Date: Mon, 10 Aug 2020 02:38:07 +0000 [thread overview]
Message-ID: <20200810023807.9260-1-vulab@iscas.ac.cn> (raw)
A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "devm_kcalloc".
