Since commit 7723f4c5 ("driver core: platform: Add an error message to platform_get_irq*()") and commit 2043727c ("driver core: platform: Make use of the helper function dev_err_probe()"), there is no need to call the dev_err() function directly to print a custom message when handling an error from platform_get_irq() function as it is going to display an appropriate error message in case of a failure.

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct ep93xx_dma_engine.

With the possibility of multiple wq drivers that can be bound to the wq, the user config tool accel-config needs a way to know which wq driver to bind to the wq. Introduce per wq driver_name sysfs attribute where the user can indicate the driver to be bound to the wq. This allows accel-config to just bind to the driver using wq->driver_name. Signed-off-by:

Commit e39a2329 ("Kconfig: Allow k3dma driver to be selected for more then HISI3xx platforms") expanded the "depends on" line of K3_DMA from "ARCH_HI3xxx" to "ARCH_HI3xxx || ARCH_HISI || COMPILE_TEST". However, ARCH_HI3xxx implies ARCH_HISI, so it's unnecessary to list both. Instead, just list ARCH_HISI, which covers all HiSilicon platforms. Signed-off-by:

idxd sub-drivers belong to bus dsa_bus_type. Thus, dsa_bus_type must be registered in dsa bus init before idxd drivers can be registered. But the order is wrong when both idxd and idxd_bus are builtin drivers. In this case, idxd driver is compiled and linked before idxd_bus driver. Since the initcall order is determined by the link order, idxd sub-drivers are registered in idxd initcall before dsa_bus_type is registered in idxd_bus initcall. idxd initcall fails: [ 21.562803] calling idxd_init_module+0x0/0x110 @ 1 [ 21.570761] Driver 'idxd' was unable to register with bus_type 'dsa' because the bus was not initialized.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:
