From 8d2e77b39b8fecb794e19cd006a12f90b14dd077 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Wed, 4 Dec 2019 04:35:25 +0100 Subject: HID: alps: Fix an error handling path in 'alps_input_configured()' They are issues: - if 'input_allocate_device()' fails and return NULL, there is no need to free anything and 'input_free_device()' call is a no-op. It can be axed. - 'ret' is known to be 0 at this point, so we must set it to a meaningful value before returning Fixes: 2562756dde55 ("HID: add Alps I2C HID Touchpad-Stick support") Signed-off-by: Christophe JAILLET Signed-off-by: Jiri Kosina --- drivers/hid/hid-alps.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/hid/hid-alps.c') diff --git a/drivers/hid/hid-alps.c b/drivers/hid/hid-alps.c index ae79a7c66737..fa704153cb00 100644 --- a/drivers/hid/hid-alps.c +++ b/drivers/hid/hid-alps.c @@ -730,7 +730,7 @@ static int alps_input_configured(struct hid_device *hdev, struct hid_input *hi) if (data->has_sp) { input2 = input_allocate_device(); if (!input2) { - input_free_device(input2); + ret = -ENOMEM; goto exit; } -- cgit
