[PATCH 00/52] serial: Convert to platform remove callback returning void

Hello, this series starts with two fixes. The first one fixes a resource leak and use after free. The second only improves error reporting. I added a Fixes: marker to these. I let you decide if you want to drop them (or the second only) or add a Cc: stable (to both or only the first one). After t

[PATCH 51/52] serial: ucc: Convert to platform remove callback returning void

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve h

get_user_pages() and EXEC_ONLY mapping.

Hello, Some architectures can now support EXEC_ONLY mappings and I am wondering what get_user_pages() on those addresses should return. Earlier PROT_EXEC implied PROT_READ and pte_access_permitted() returned true for that. But arm64 does have this explicit comment that says /* * p??_access_pe
