Subject: [PATCH 5.15 02/28] clocksource/drivers/ixp4xx: remove __init from ixp4xx_timer_setup()
Date: Thu, 30 Jun 2022 15:46:58 +0200	[thread overview]
Message-ID: <20220630133233.000575254@linuxfoundation.org> (raw)
In-Reply-To: <20220630133232.926711493@linuxfoundation.org>

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.
