From f6ac438e5e9d8052b07ebe43673b88f0496fed8d Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Fri, 9 Jun 2017 13:41:32 +0200 Subject: [PATCH] gpio: mockup: use devm_kcalloc() where applicable When allocating a zeroed array of objects use devm_kcalloc() instead of manually calculating the required size and using devm_kzalloc().
