If probe is reached, we've already matched the device and in the case of DT matching, the struct device_node pointer will be set. Therefore, there is no need to call of_match_device() in probe. Signed-off-by:

Use preferred device_get_match_data() instead of of_match_device() to get the driver match data. With this, adjust the includes to explicitly include the correct headers. Signed-off-by:

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 checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). To do so, the code needs a little shuffling related to how hw_desc is used and nb_desc incremented. The one by one increment is needed for the error handling path, calling pxad_free_desc(), to work correctly. So, add a new intermediate variable, desc, to store the result of the dma_pool_alloc() call. Signed-off-by:

If pxad_alloc_desc() fails on the first dma_pool_alloc() call, then sw_desc->nb_desc is zero. In such a case pxad_free_desc() is called and it will BUG_ON(). Remove this erroneous BUG_ON(). It is also useless, because if "sw_desc->nb_desc == 0", then, on the first iteration of the for loop, i is -1 and the loop will not be executed. (both i and sw_desc->nb_desc are 'int') Fixes: a57e16cf ("dmaengine: pxa: add pxa dmaengine driver") Signed-off-by:

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.
