mfd: da9055: Simplify the error handling path in da9055_device_init()

2025-11-06T14:05:02+00:00

If mfd_add_devices() fails, there is no need to call mfd_remove_devices(). The needed clean-up is already done in the error handling path of mfd_add_devices(). So, remove the unneeded (and harmless) call.

mfd: da9055: Fix missing regmap_del_irq_chip() in error path

2025-11-06T14:03:52+00:00

When da9055_device_init() fails after regmap_add_irq_chip() succeeds but mfd_add_devices() fails, the error handling path only calls mfd_remove_devices() but forgets to call regmap_del_irq_chip(). This results in a resource leak. Fix this by adding regmap_del_irq_chip() to the error path so that resources are released properly.

mfd: dialog: Convert to use maple tree register cache

2024-02-23T14:58:04+00:00

The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache.

mfd: da9055: Remove MODULE_LICENSE in non-modules

2023-04-26T10:40:31+00:00

Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules. Signed-off-by: Nick Alcock Suggested-by: Luis Chamberlain Signed-off-by: Lee Jones

mfd: da9xxx-core: Constify static struct resource

2020-11-19T08:34:21+00:00

Constify a number of static struct resource. The only usage of the structs are to assign their address to the resources field in the mfd_cell struct. This allows the compiler to put them in read-only memory. Done with the help of Coccinelle. Signed-off-by: Rikard Falkeborn Acked-by: Adam Thomson Signed-off-by: Lee Jones

devicetree: Dialog Semiconductor consolidate existing vendor prefixes to standardise on 'dlg'

2014-08-29T08:26:29+00:00

This patch series updates the device tree vendor prefix for Dialog Semiconductor. Various methods are currently used throughout the kernel: 'diasemi', 'dialog' and 'dlg'. Others have also been suggested. This patch set aims to consolidate the usage of the vendor prefix to use a common standard. The prefix 'dlg' is used.

mfd: dialog: Constify struct mfd_cell where possible

As of commit 03e361b25ee8dfb1fd9b890072c23c4aae01c6c7 ("mfd: Stop setting refcounting pointers in original mfd_cell arrays"), the "cell" parameter of mfd_add_devices() is "const" again. Hence make all cell data passed to mfd_add_devices() const where possible. Signed-off-by: Geert Uytterhoeven Signed-off-by: Lee Jones
