Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

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

2026-02-21T09:02:28+00:00

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

fbdev: omapfb: Make FB_DEVICE dependency optional

2026-02-14T10:09:46+00:00

omapfb provides several sysfs interfaces for framebuffer configuration and debugging, but these are not required for the core driver. Remove the hard dependency on CONFIG_FB_DEVICE and make sysfs support optional by using dev_of_fbinfo() to obtain the backing device at runtime. When FB_DEVICE is disabled, sysfs operations are skipped while the code still builds and is type-checked.

fbdev: omapfb: Add 'plane' value check

2025-03-26T21:39:21+00:00

Function dispc_ovl_setup is not intended to work with the value OMAP_DSS_WB of the enum parameter plane. The value of this parameter is initialized in dss_init_overlays and in the current state of the code it cannot take this value so it's not a real problem. For the purposes of defensive coding it wouldn't be superfluous to check the parameter value, because some functions down the call stack process this value correctly and some not. For example, in dispc_ovl_setup_global_alpha it may lead to buffer overflow. Add check for this value. Found by Linux Verification Center (linuxtesting.org) with SVACE static analysis tool.

Value of enum parameter 'plane' is initialized in dss_init_overlays and cannot take the value OMAP_DSS_WB. Function dispc_ovl_setup_common could be called with this value of parameter only from dispc_wb_setup, which has never been used and has been removed in commit 4f55bb03801a ("omapfb: Remove unused writeback code"). The code in the if-branch is unreachable. Remove unreachable branch. Found by Linux Verification Center (linuxtesting.org) with SVACE static analysis tool.

fbdev: omapfb: Use syscon_regmap_lookup_by_phandle_args

2025-01-12T17:12:35+00:00

Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over syscon_regmap_lookup_by_phandle() combined with getting the syscon argument. Except simpler code this annotates within one line that given phandle has arguments, so grepping for code would be easier. There is also no real benefit in printing errors on missing syscon argument, because this is done just too late: runtime check on static/build-time data. Dtschema and Devicetree bindings offer the static/build-time check for this already. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Helge Deller
