From: Laurent Pinchart Date: Tue, 20 Jan 2015 22:55:42 +0000 (+0200) Subject: usb: isp1760: Retrieve pdev memory resource from hcd at remove time X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fcead8431d245af312afcbcbfbfc34a0fec77cd9;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git usb: isp1760: Retrieve pdev memory resource from hcd at remove time The platform driver remove function needs to release the memory resource requested at probe time. Instead of retrieving the resource from the platform device, retrieve it from the usb_hcd. This mimics the behaviour of the PCI and OF glues, and will make it easier to share code between all three glue layers.
