Thank you for the patches fixing this.

I'm going to wait a bit with applying these to give other people who have looked at these issues a chance to review these patches (added Dan Carpenter and Christophe JAILLET to the To: list).

For future patches please write one patch for each issue you are addressing instead of one patch per file. Since the fixes are the same for all 5 files in this case that would have meant doing 2 patches:

1. To fix the memory leak errors in all 5 files
2. To fix the uninitialized variable in all 5 files.

There is no need to send a new version unless changes are requested by one of the reviewers, I'll just squash all these 5 patches into 1 patch when merging this (and keep the uninitialized variable changes as part of the same patch).

Also these patches should have something like this as part of the commit msg (directly above your Signed-off-by:) :

Reported-by: Dan Carpenter <dan.carpenter@...aro.org>
Closes: https://lore.kernel.org/platform-driver-x86/176e14a2-41f8-41b2-854e-77319ec2416d@moroto.mountain/

Regards,

Hans
