From 98ec880a8598f2073dc263d02c5672df6a8d587f Mon Sep 17 00:00:00 2001 From: Zizhi Wo Date: Thu, 4 Sep 2025 10:39:55 +0800 Subject: [PATCH] tty/vt: Add missing return value for VT_RESIZE in vt_ioctl() [ Upstream commit da7e8b3823962b13e713d4891e136a261ed8e6a2 ] In vt_ioctl(), the handler for VT_RESIZE always returns 0, which prevents users from detecting errors. Add the missing return value so that errors can be properly reported to users like vt_resizex().
