+Subject: clocksource/drivers/ixp4xx: remove EXPORT_SYMBOL_GPL from ixp4xx_timer_setup()
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+ixp4xx_timer_setup is exported, and so can not be an __init function.
+But it does not need to be exported as it is only called from one
+in-kernel function, so just remove the EXPORT_SYMBOL_GPL() marking to
+resolve the build warning.
+
+This is fixed "properly" in commit 41929c9f628b
+("clocksource/drivers/ixp4xx: Drop boardfile probe path") but that can
+not be backported to older kernels as the reworking of the IXP4xx
+codebase is not suitable for stable releases.
