Subject: [PATCH 0/3] serial: 8250_aspeed_vuart: fix duplicate __release_region() on unbind
Date: Sun, 9 May 2021 20:42:28 -0500 [thread overview]
Message-ID: <20210510014231.647-1-zev@bewilderbeest.net> (raw)
Hello,
This series addresses a bug reported by Andrew Jeffery [0] wherein the
aspeed-vuart driver triggers a "Trying to free nonexistent resource"
warning from __release_region() when unbound from a device. The first
two patches provide some preparatory refactoring and cleanups; the
actual fix is in the final patch.
Joel, note that this series has a dependency on the "generalized DT
properties" series [1] (specifically the second patch), which has been
merged upstream but is not yet in the OpenBMC dev-5.10 tree.
