Carles Cufi 8c748fd005 kernel: Modify the signature of k_mem_slab_free() 
Modify the signature of the k_mem_slab_free() function with a new one,
replacing the old void **mem with void *mem as a parameter.

The following function:
void k_mem_slab_free(struct k_mem_slab *slab, void **mem);

has the wrong signature. mem is only used as a regular pointer, so there
is no need to use a double-pointer. The correct signature should be:
void k_mem_slab_free(struct k_mem_slab *slab, void *mem);

The issue with the current signature, although functional, is that it is
extremely confusing. I myself, a veteran Zephyr developer, was confused
by this parameter when looking at it recently.

All in-tree uses of the function have been adapted.

Fixes #61888.

Piotr Mienkowski 4566d0ec58 drivers: i2s_sam_ssc: use dma_reload() to continue transfer 
Use `dma_reload()` instead of `dma_config()` within DMA callbacks. This
significantly shortens time required to reconfigure DMA engine to
transmit / receive the next data block and allows to configure higher
I2S bus data rates.

The maximum I2S data rate supported by the driver is still lower than
that of underlying hardware. To fully support hardware capabilities the
I2S driver would have to use scatter-gather / linked-list DMA transfer.
This is currently not supported by the DMA driver.

Tomasz Bursztyka 4dcfb5531c isr: Normalize usage of device instance through ISR 
The goal of this patch is to replace the 'void *' parameter by 'struct
device *' if they use such variable or just 'const void *' on all
relevant ISRs

This will avoid not-so-nice const qualifier tweaks when device instances
will be constant.

Note that only the ISR passed to IRQ_CONNECT are of interest here.

In order to do so, the script fix_isr.py below is necessary:
