Tzung-Bi: I queued these two for fixes. Please resend patch 04/23 separately
so that I can queue it for v6.19 as well. 01/23 and 03/23 risk impacting a
very fragile path in GPIOLIB so any changes to it will have to wait until
v7.0-rc1 to give it a lot of time in next.
[02/23] gpiolib: cdev: Fix resource leaks on errors in gpiolib_cdev_register()
commit: be037ec1785d76351037103ce6baddd3299606ee
[05/23] gpiolib: cdev: Correct return code on memory allocation failure
commit: c7843298bf973d4bc7f4346140661e117186decc
