From d9bc4a8539a518636cd70d498e94787e32ea8fbe Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 13 Jan 2017 13:37:25 +0100 Subject: spi: fsl: Use kmalloc_array() in of_fsl_spi_get_chipselects() A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software.
