From ace56935ff48879239d79129c7882ea2ff1b4804 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Fri, 23 Mar 2018 09:34:51 -0700 Subject: [PATCH] gpiolib: Change bitmap allocation to kmalloc_array We don't need to clear out these bits when we set them immediately after. Use kmalloc_array() to skip clearing the bits.
