The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >>From 0631fb8b027f5968c2f5031f0b3ff7be3e4bebcc Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Wed, 15 Nov 2017 13:00:45 -0800 Subject: firmware: vpd: Fix platform driver and device registration/unregistration The driver exit function needs to unregister both platform device and driver. Also, during registration, register driver first and perform error checks.
