Pull staging driver updates from Greg KH: "Here is the "big" set of staging driver changes for 7.1-rc1. Nothing major in here at all, just lots of little cleanups for the staging drivers, driven by new developers getting their feet wet in kernel development. "Largest" thing in here is the change of some of the octeon variable types into proper kernel ones. Full details are in the shortlog. All of these have been in linux-next for a while with no reported issues" * tag 'staging-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (154 commits) staging: rtl8723bs: remove redundant & parentheses staging: most: dim2: replace BUG_ON() in poison_channel() staging: most: dim2: replace BUG_ON() in enqueue() staging: most: dim2: replace BUG_ON() in configure_channel() staging: most: dim2: replace BUG_ON() in service_done_flag() staging: most: dim2: replace BUG_ON() in try_start_dim_transfer() staging: rtl8723bs: remove unused RTL8188E antenna selection macros staging: rtl8723bs: remove redundant blank lines in basic_types.h staging: rtl8723bs: wrap complex macros with parentheses staging: rtl8723bs: remove unused WRITEEF/READEF byte macros staging: rtl8723bs: rename camelCase variable staging: greybus: audio: fix error message for BTN_3 button staging: rtl8723bs: rename variables to snake_case staging: rtl8723bs: fix spelling in comment staging: rtl8723bs: cleanup return in sdio_init() staging: rtl8723bs: use direct returns in sdio_dvobj_init() staging: rtl8723bs: remove unused arg at odm_interface.h greybus: raw: fix use-after-free if write is called after disconnect greybus: raw: fix use-after-free on cdev close staging: rtl8723bs: fix logical continuations in xmit_linux.c ...

staging: vme_user: replace deprecated mmap hook with mmap_prepare

2026-04-05T20:53:44Z

The f_op->mmap interface is deprecated, so update driver to use its successor, mmap_prepare. The driver previously used vm_iomap_memory(), so this change replaces it with its mmap_prepare equivalent, mmap_action_simple_ioremap(). Functions that wrap mmap() are also converted to wrap mmap_prepare() instead. Also update the documentation accordingly.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00Z

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

vme_bus_match takes a const pointer and casts it away with container_of() which is generally not a good idea. Fix this up by properly marking the output as const. Link: https://lore.kernel.org/r/2025052132-giddiness-slain-5ba1@gregkh Signed-off-by: Greg Kroah-Hartman
