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

usb: musb: cppi41: Switch to use hrtimer_setup()

2025-02-18T10:19:02+00:00

hrtimer_setup() takes the callback function pointer as argument and initializes the timer completely. Replace hrtimer_init() and the open coded initialization of hrtimer::function with the new setup mechanism. Patch was created by using Coccinelle.

usb: musb: cppi41: Switch to use dev_err_probe() helper

2022-09-27T08:36:06+00:00

In the probe path, dev_err() can be replaced with dev_err_probe() which will check if error code is -EPROBE_DEFER and prints the error name. It also sets the defer probe reason which can be checked later through debugfs. It's more simple in error path.

usb: musb: remove duplicated quirks flag

2018-05-22T10:03:24+00:00

Both musb_io and musb_platform_ops in struct musb define a quirks flag for the same purpose. Let's remove the one in struct musb_io, and use that in struct musb_platform_ops instead. Signed-off-by: Bin Liu Signed-off-by: Greg Kroah-Hartman

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

usb: musb: musb_cppi41: Configure the number of channels for DA8xx

2017-10-17T09:42:51+00:00

Currently, the number of channels is set to 15 but in the case of DA8xx, the number of channels is 4. Update the driver to configure the number of channels at runtime.

2017-10-17T09:42:51+00:00

The way to configure the DMA mode on DA8xx is different from DSPS. Add a new function to configure DMA mode on DA8xx and use a callback to call the right function based on the platform.

usb: musb: musb_cppi41: Fix the address of teardown and autoreq registers

2017-10-17T09:42:51+00:00

The DA8xx and DSPS platforms don't use the same address for few registers. On Da8xx, this is causing some issues (e.g. teardown that doesn't work). Configure the address of the register during the init and use them instead of constants.
