From 09e15086936e01d7588020be37ea724116bcefec Mon Sep 17 00:00:00 2001 From: Xiongfeng Wang Date: Thu, 9 Nov 2017 14:22:39 +0800 Subject: ACPI / utils: Fix memory leak in acpi_evaluate_reference() error path When package.count is larger than ACPI_MAX_HANDLES, buffer.pointer is not freed before the function returns AE_NO_MEMORY. Fix this possible memory leak by kfree'ing it. Signed-off-by: Xiongfeng Wang Signed-off-by: Rafael J.
