From: Nathan Chancellor <nathan@xxxxxxxxxx> Subject: hexagon: export raw I/O routines for modules Patch series "Fixes for ARCH=hexagon allmodconfig", v2. This series fixes some issues noticed with ARCH=hexagon allmodconfig. This patch (of 3): 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.
