Subject: platform_driver's probe functions must not be located in .init.text

Hello,

if the probe function of a platform_driver lives in .init.text (i.e. is
defined using __init) registering a device after the .init sections are
discarded results in an oops. You can test that by doing

echo $drivername.$somevalidid > /sys/bus/platform/drivers/$drivername/unbind
echo $drivername.$somevalidid > /sys/bus/platform/drivers/$drivername/bind

As a reply to this mail I send 62 patches that fix this kind of error by
moving the respective probe functions to .devinit.text.

This should be safe in general as it only increases the lifetime for the
respective functions.

The alternative is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver. But I choosed changing the section as
this is less intrusive though probably the latter would be the better
fix because it saves some memory.

You cannot blindly change to use platform_driver_probe because if the
devices are only registered after that call (but while .init is still
valid) the driver is already gone. This is hardly checkable for me
because I don't have the hardware for most drivers I fixed.

Shortlog and diffstat are below. You can fetch this series from

git://git.pengutronix.de/git/ukl/linux-2.6.git platsection-master

based on v2.6.29-rc1.

Best regards
Uwe

Subject: [PATCH] move corgi-ts's probe function to .devinit.text

A pointer to corgits_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

Subject: [PATCH] move mmci-omap's probe function to .devinit.text

A pointer to mmc_omap_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

Subject: [PATCH] move sgivwfb's probe function to .devinit.text

A pointer to sgivwfb_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

For now, yes, it is.

One reason is that my script to find errors doesn't trigger for that.

Another is that this is not that critical. If the probe function is in
.init.text you can get an oops. If remove is in .text it just occupies
RAM without being used (if HOTPLUG=n). And if remove is in .exit.text
and is properly wrapped in __exit_p when assigning .remove everything is
fine, too, you just cannot remove a device.

Maybe I will address this in later series.

Best regards
Uwe

Thank you for the patch!

Is that solution better? What are the pros/cons?

When using platform_driver_probe only devices that are already available
are probed. There is no way you can bind a device that was registered
after the call to platform_driver_probe or that was once unbound via
sysfs. In return your .probe function can live in .init.text and so you
can save some RAM. (Note, that for modular drivers the situation is a
bit different because you can reload your modules (assuming it supports
unloading) and then you get a new platform_driver_probe call. This
doesn't matter though, because either the devices are available before
you can load your module or your module creates the devices itself.)

I think for many drivers using platform_driver_probe is the more
sensible way, but it needs a deeper look and/or more testing. With the
unfixed code a device that is created after platform_driver_register but
before the init sections are discarded is correctly bound. After
changing to platform_driver_probe this is not the case anymore. That's
why I choosed to stay with platform_driver_register for my patches.

Best regards
Uwe
