    Subject[PATCH 4.4 142/162] hexagon: export raw I/O routines for modules
    Date
    From: Nathan Chancellor <nathan@kernel.org>

    commit ffb92ce826fd801acb0f4e15b75e4ddf0d189bde upstream.

    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.
