mtd: physmap: Drop leftovers of removed code for Baikal SoC

2026-03-16T16:23:33+00:00

The previous clean up killed the driver along with dropping some calls but missed one place to drop. Do it here.

mtd: physmap_of_gemini: Fix disabled pinctrl state check

2026-03-11T15:19:50+00:00

The condition for checking the disabled pinctrl state incorrectly checks gf->enabled_state instead of gf->disabled_state. This causes misleading error messages and could lead to incorrect behavior when only one of the pinctrl states is defined. Fix the condition to properly check gf->disabled_state.

mtd: physmap: physmap-bt1-rom: Remove not-going-to-be-supported code for Baikal SoC

2026-03-11T15:18:53+00:00

As noticed in the discussion [1] the Baikal SoC and platforms are not going to be finalized, hence remove stale code. Link: https://lore.kernel.org/lkml/22b92ddf-6321-41b5-8073-f9c7064d3432@infradead.org/ [1] Reviewed-by: Randy Dunlap Signed-off-by: Andy Shevchenko Signed-off-by: Miquel Raynal

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

2026-02-22T01:09:51+00:00

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'. 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

mtd: physmap-core: Prioritize ofparts for OF probe

2026-01-29T19:11:15+00:00

Place the ofparts before RedBoot partitions in the OF probe path: this makes it possible to override any existing RedBoot partitions with fixed-partitions which may be necessary, such as when you need to repartition the flash from Linux' point of view but not necessary from the bootloaders point of view. This happens when a device such as Raidsonic IB-4220-B has three partitions named "Kern", "Ramdisk" and "Application" that we want to merge into one for more efficient use of the flash memory in OpenWrt.

mtd: maps: pcmciamtd: fix potential memory leak in pcmciamtd_detach()

2025-11-17T10:49:14+00:00

The memory allocated for struct pcmciamtd_dev in pcmciamtd_probe() is not freed in the corresponding remove function pcmciamtd_detach(). Fix that by freeing it in the remove function. Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Signed-off-by: Abdun Nihaal Signed-off-by: Miquel Raynal

mtd: Switch back to struct platform_driver::remove()

2024-10-21T09:58:07+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/mtd to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.
