[PATCH 2/2] amba: Initialize dma_parms for amba devices

by Ulf Hansson

It's currently the amba driver's responsibility to initialize the pointer, dma_parms, for its corresponding struct device. The benefit with this approach allows us to avoid the initialization and to not waste memory for the struct device_dma_parameters, as this can be decided on a case by case basis. However, it has turned out that this approach is not very practical. Not only does it lead to open coding, but also to real errors. In principle callers of dma_set_max_seg_size() doesn't check the error code, but just assumes it succeeds. For these reasons, let's do the initialization from the common amba bus at the device registration point. This also follows the way the PCI devices are being managed, see pci_device_add().

This is a note to let you know that I've just added the patch titled USB: serial: option: add BroadMobi BM806U to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-testing branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the usb-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From 6cb2669cb97fc4fdf526127159ac59caae052247 Mon Sep 17 00:00:00 2001 From: Pawel Dembicki <paweldembicki(a)gmail.com> Date: Wed, 25 Mar 2020 06:44:18 +0100 Subject: USB: serial: option: add BroadMobi BM806U BroadMobi BM806U is an Qualcomm MDM9225 based 3G/4G modem.
