Merge tag 'char-misc-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

2026-08-25T16:38:50+00:00

Pull char/misc/IIO/etc driver updates from Greg KH:
 "Here is the big set of char, misc, iio, counter, fpga, and other small
  driver subsystems for 7.3-rc1.

  Overall, due to some driver removals we only added a bit more code
  than removed, which was a nice change. Highlights in this merge
  request are:

   - Loads of IIO driver updates and additions

   - binder driver updates (more on that below...)

   - Removal of the SGI XP and GRU drivers as they are not used anymore
     and turn out to be pretty insecure overall

   - Removal of the obsolete ibmasm driver as it's not being used
     anymore

   - Coresight driver updates and additions

   - Mei driver udpates

   - Counter driver updates

   - FPGA driver updates

   - ICC driver updates

   - lots and lots of other tiny driver updates to resolve reported
     issues

  All of these have been in linux-next for a while"

ASoC: stm: stm32_spdifrx: Drop redundant error messages

2026-07-29T23:19:51+00:00

Both devm_request_irq() and snd_dmaengine_pcm_register() already log
failures internally. Drop the redundant error messages and return the
original errors directly.

iio: inkern: Use namespaced exports

2026-07-05T00:37:19+00:00

Use namespaced exports for IIO consumer API functions.

This will make it easier to manage the IIO export surface. Consumer drivers
will only be provided access to a specific set of functions, thereby
restricting usage of internal IIO functions by other parts of the kernel.

This change cannot be split into several parts without breaking
bisectability, thus all of the affected drivers are modified at once.

ASoC: stm: stm32_adfsdm: set debugfs_prefix via Component driver

2026-06-10T11:21:13+00:00

We can set component->debugfs_prefix via component_driver->debugfs_prefix.
Use it.

Now it no longer need to use snd_soc_component_initialize() /
snd_soc_component_add(). Use snd_soc_component_register() instead.
