HSI: cmt_speech: convert mmap hook to mmap_prepare, refactor

2026-10-24T08:56:15+00:00

Use the mmap_prepare in favour of the deprecated mmap hook as part of the
work to convert one to another.

Since this is simply a refcounted kernel page that has been allocated, it
should not be marked VM_IO and should be inserted using the kernel page
insertion mechanism, so convert it to do this instead.

Use the VMA descriptor's private data field as a scratch buffer to store
the page in - this stays valid throughout the kernel page mapping
operation.

hsi: omap_ssi_core: fix missing DMA mask setup for SSI controller device

2026-07-26T00:20:07+00:00

The OMAP SSI driver uses a synthetic HSI controller device allocated via
hsi_alloc_controller(), which does not go through the normal OF/platform
device initialization path.

As a result, the embedded struct device does not have a DMA mask
initialized by default.

After recent DMA API hardening changes, dma_map_sg() and related helpers
now require a valid dma_mask to be present, otherwise the driver may
crash or trigger warnings when attempting DMA mapping operations.

Fix this by explicitly initializing the DMA mask for the SSI controller
device and setting a 32-bit DMA mask, which matches the hardware
capabilities.

Since commit 55b48e23f5c4 ("genirq/devres: Add error handling in
devm_request_*_irq()"),
devm_request_irq() and devm_request_threaded_irq() automatically log
detailed error messages on failure. Remove the now-redundant
driver-specific dev_err() calls.

hsi: omap_ssi: remove debugfs on port creation failure

2026-07-26T00:17:34+00:00

ssi_probe() creates the controller debugfs tree before creating the SSI
port child devices. If a port device cannot be created, the error path
removes any children and tears down the controller, but leaves the
debugfs tree behind.

Remove the controller debugfs tree on the port creation failure path,
matching the normal remove path.

Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of  by the more specific
 where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.
