From fd571ef413ed63b84e02e2e598839222c4a58f28 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Sat, 12 Jul 2025 17:00:06 +0900 Subject: [PATCH] seq: fix return value when failing devnode detection of ALSA Sequencer character device MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When failing detecting devnode of ALSA Sequencer character device, the helper function returns negative value to the callers. This is overlooked in the previous code refactoring. It should return FALSE. This bug brings the following compiler warnings: ../src/seq/query.c: In function ‘alsaseq_get_system_info’: ../src/seq/query.c:113:9: warning: ‘fd’ may be used uninitialized [-Wmaybe-uninitialized] 113 | if (ioctl(fd, SNDRV_SEQ_IOCTL_SYSTEM_INFO, info) < 0) { | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../src/seq/query.c:101:9: note: ‘fd’ was declared here 101 | int fd; | This commit fixes the bug.
