+Subject: clocksource/drivers/ixp4xx: remove __init from ixp4xx_timer_setup()
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+ixp4xx_timer_setup is exported, and so can not be an __init function.
+Remove the __init marking as the build system is rightfully claiming
+this is an error in older kernels.
+
+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.
