Subject: Back-ports of dwc2 commit break peripheral-only builds
Date: Fri, 28 May 2021 11:19:00 +0100	[thread overview]
Message-ID: <558ce64c-666a-5b68-ee48-74293b08cbbc@raspberrypi.com> (raw)

Hi,

Back-ports of [1] - a Fix to the dwc2 driver - cause build errors for 
configurations including CONFIG_USB_DWC2_PERIPHERAL=y because in the stable 
branches the bus_suspended member of struct dwc2_hsotg is not present with that 
setting. [1] depends on [2] to move bus_suspended into a common part of 
dwc2_hsotg, but because [2] is not a fix it hasn't been back-ported to stable 
branches. [2] does not apply cleanly on its own (e.g. to linux-5.10.y) , so 
either more commits must be back-ported, [1] must be reverted, or a subset of 
[2] could be used for the back-ports.

Phil
