From 2984e7a102aec85a39827b314bc898ebb5d2fdb9 Mon Sep 17 00:00:00 2001 From: Przemyslaw Marczak Date: Tue, 31 Mar 2015 18:57:16 +0200 Subject: [PATCH] dm: gpio: request list: return the count if requests max_count reached The function gpio_request_list_by_name_nodev() returned -ENOSPC error, when the loop count was greater than requested count. This was wrong, because function should return the requested gpio count, when meets the call request without errors. Now, the loop ends on requested max_count.
