From 128497456756e1b952bd5a912cd073836465109d Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 26 Jan 2026 16:38:45 +0200 Subject: [PATCH] platform/x86: toshiba_haps: Fix memory leaks in add/remove routines toshiba_haps_add() leaks the haps object allocated by it if it returns an error after allocating that object successfully. toshiba_haps_remove() does not free the object pointed to by toshiba_haps before clearing that pointer, so it becomes unreachable allocated memory. Address these memory leaks by using devm_kzalloc() for allocating the memory in question. Fixes: 23d0ba0c908a ("platform/x86: Toshiba HDD Active Protection Sensor") Signed-off-by: Rafael J.
