From a550d6ae4d73dc4b9f1a2b3ad3d8d9e355b396be Mon Sep 17 00:00:00 2001 From: Jiapeng Chong Date: Fri, 9 Aug 2024 16:05:23 +0800 Subject: pwm: lp3943: Fix an incorrect type in lp3943_pwm_parse_dt() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The return value from the call to of_property_count_u32_elems() is int. However, the return value is being assigned to an u32 variable 'num_outputs', so making 'num_outputs' an int. ./drivers/pwm/pwm-lp3943.c:238:6-17: WARNING: Unsigned expression compared with zero: num_outputs <= 0.
