Subject: [PATCH] Hexagon: Export raw I/O routines for modules
Date: Thu, 8 Jul 2021 16:38:50 -0700 [thread overview]
Message-ID: <20210708233849.3140194-1-nathan@kernel.org> (raw)
When building ARCH=hexagon allmodconfig, the following errors occur:
ERROR: modpost: "__raw_readsl" [drivers/i3c/master/svc-i3c-master.ko] undefined!
ERROR: modpost: "__raw_writesl" [drivers/i3c/master/dw-i3c-master.ko] undefined!
ERROR: modpost: "__raw_readsl" [drivers/i3c/master/dw-i3c-master.ko] undefined!
ERROR: modpost: "__raw_writesl" [drivers/i3c/master/i3c-master-cdns.ko] undefined!
ERROR: modpost: "__raw_readsl" [drivers/i3c/master/i3c-master-cdns.ko] undefined!
Export these symbols so that modules can use them without any errors.
Fixes: 013bf24c3829 ("Hexagon: Provide basic implementation and/or stubs for I/O routines.")

It would be nice if this could get into 5.14 at some point so that we
can build ARCH=hexagon allmodconfig in our CI.
