2022-02-04greybus: svc: clean up link configuration hack at helloJohan Hovold1-5/+8
Commit ee2f2074fdb2 ("greybus: svc: reconfig APBridgeA-Switch link to handle required load") added a temporary hack which reconfigures the link at HELLO by abusing the deferred request processing mechanism. Restructure the HELLO request processing so that the link-configuration work is queued before creating the debugfs files and add a comment explaining why it's there.

2022-02-04greybus: svc: clean up hello error pathJohan Hovold1-2/+3
While currently safe, it is unnecessary (and confusing) to try to destroy the watchdog when watchdog creation fails. Change the corresponding error path to only deregister the svc.

2019-08-27staging: greybus: move the greybus core to drivers/greybusGreg Kroah-Hartman1-0/+1397
The Greybus core code has been stable for a long time, and has been shipping for many years in millions of phones. With the advent of a recent Google Summer of Code project, and a number of new devices in the works from various companies, it is time to get the core greybus code out of staging as it really is going to be with us for a while.
