From 7bdbd1eccc9fb3875f33af1a2257001128824e81 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 18 Jul 2019 15:51:01 +0900 Subject: [PATCH] gpio: refactor gpiochip_allocate_mask() with bitmap_alloc() Refactor gpiochip_allocate_mask() slightly by using bitmap_alloc(). I used bitmap_free() for the corresponding free parts. Actually, bitmap_free() is a wrapper of kfree(), but I did this for consistency.
