[PATCH] HID: elan: Fix some error handling path
From: Christophe JAILLET <hidden>
Date: 2020-11-29 08:24:22
Also in:
kernel-janitors, lkml
Subsystem:
hid core layer, the rest · Maintainers:
Jiri Kosina, Benjamin Tissoires, Linus Torvalds
'input' is a managed resource allocated earlier in the function by:
input = devm_input_allocate_device(&hdev->dev);
There is no need to explicitly free it. This would lead to a double
reference decrement.
Fixes: b7429ea53d6c ("HID: elan: Fix memleak in elan_input_configured")
Fixes: 9a6a4193d65b ("HID: Add driver for USB ELAN Touchpad")
