Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

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

pinctrl: core: Remove duplicate error messages

pinctrl_claim_hogs() is covered to report any error via message. Since that it's not needed in the callers. Signed-off-by: Andy Shevchenko Reviewed-by: Bartosz Golaszewski Signed-off-by: Linus Walleij

pinctrl: core: Simplify devm_pinctrl_*()

2026-02-03T00:18:18+00:00

Use devm_add_action_or_reset() instead of devres_alloc() and devres_add(), which works the same. This will simplify the code. There is no functional changes. Signed-off-by: Andy Shevchenko Reviewed-by: Bartosz Golaszewski Signed-off-by: Linus Walleij

pinctrl: cix: sky1: Provide pin control dummy states

2025-11-05T17:13:33+00:00

This exports and calls the pinctrl_provide_dummies() function from the CIX SKY1 driver. The reasons are explained in a comment in the commit, in essence the two pin controllers need to go through explicit state transitions default->sleep->default despite they only handle one single state each.

pinctrl: Demote subsystem banner message

There is no reason to print any "hello world" from pin control unless (maybe) if we are debugging. Drop the banner. Reviewed-by: Bartosz Golaszewski Signed-off-by: Linus Walleij

pinctrl: Add pinctrl_pm_select_init_state helper function

2025-08-27T13:23:30+00:00

If a platform requires an initial pinctrl state during probing, this helper function provides the client with access to the same initial state. eg: xxx_suspend_noirq ... pinctrl_pm_select_sleep_state xxx resume_noirq pinctrl_pm_select_init_state ... pinctrl_pm_select_default_state Signed-off-by: Christian Bruel Signed-off-by: Manivannan Sadhasivam Reviewed-by: Linus Walleij Link: https://patch.msgid.link/20250820075411.1178729-3-christian.bruel@foss.st.com

pinctrl: Constify pointers to 'pinctrl_desc'

2025-06-18T11:26:36+00:00

Pin controller core code only stores the pointer to 'struct pinctrl_desc' and does not modify it anywhere. The pointer can be changed to pointer to const which makes the code safer, explicit and later allows constifying 'pinctrl_desc' allocations in individual drivers.
