From 1be0593f05e25d56a8f65586ea6d9afa601743bc Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 25 Apr 2017 09:49:22 +0200 Subject: [PATCH] HSI: nokia-modem: Use devm_kcalloc() in nokia_modem_gpio_probe() * 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". This issue was detected by using the Coccinelle software. * Replace the specification of a data structure by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
