Subject: [PATCH v8 1/5] usb: hci: add hc_driver as argument for usb_hcd_pci_probe
Date: Mon, 23 Mar 2020 22:35:57 +0530 [thread overview]
Message-ID: <20200323170601.419809-2-vkoul@kernel.org> (raw)
In-Reply-To: <20200323170601.419809-1-vkoul@kernel.org>
usb_hcd_pci_probe expects users to call this with driver_data set as
hc_driver, that limits the possibility of using the driver_data for
driver data.
Add hc_driver as argument to usb_hcd_pci_probe and modify the callers
ehci/ohci/xhci/uhci to pass hc_driver as argument and freeup the
driver_data used
Tested xhci driver on Dragon-board RB3, compile tested ehci and ohci.
Couldn't compile uhci
