[PATCH 1/2] arm: omap: fix bug with multiple smsc911x devices

[PATCH 1/2] arm: omap: fix bug with multiple smsc911x devices

[Igor Grinberg]

kobject (c06a4250): tried to init an initialized object, something is
seriously wrong.

introduced by commit 66293989:
(omap: convert boards that use SMSC911x to use gpmc-smsc911x)

fixed by allocating struct platform_device dynamically.

Signed-off-by: Igor Grinberg <grinberg@compulab.co.il>
---
This has been boot tested with nfs root on cm-t35,
and build tested on all other affected boards.

minor suggestion: wont using pr_fmt help to reduce the need to add %s,
__func__ for pr_err through out the file?

I don't understand of what "need" are you talking about.
I don't know of any need to add "%s, __func__" with pr_fmt...
I've added "%s, __func__" as a meter of choice.
IMO, it makes it easier to parse the dmesg output.
If anyone objects it, I can remove them,
but I think both pr_fmt and __func__ are nice here and
way better then "printk(KERN_*" with embedded "smsc911x".

Allow me to rephrase.
I like the change of printk->pr_err - thanks for doing it. just
suggesting a minor improvement

if you add the following line before the #includes
#define pr_fmt(fmt) "%s: " fmt, __func__
then
-               printk(KERN_ERR "Failed to request GPIO%d for smsc911x IRQ\n",
-                               gpmc_cfg->gpio_irq);
+               pr_err("%s: Failed to request IRQ GPIO%d\n", __func__,
+                      gpmc_cfg->gpio_irq);
becomes,
-               printk(KERN_ERR "Failed to request GPIO%d for smsc911x IRQ\n",
-                               gpmc_cfg->gpio_irq);
+               pr_err("Failed to request IRQ GPIO%d\n", gpmc_cfg->gpio_irq);

Both give you exactly the output you would like to see (which I
personally prefer as well), but the second could be lesser lines of
code change ;)

Nishanth Menon

Ahh, now I understand, that can be useful indeed.
I'll send a v2...

I believe you can keep the id field uninitialized, i.e. 0.  This
applies to other boards with single smsc device as well.

[PATCH v2 1/2] arm: omap: fix bug with multiple smsc911x devices

[Igor Grinberg]

kobject (c06a4250): tried to init an initialized object, something is
seriously wrong.

introduced by commit 66293989:
(omap: convert boards that use SMSC911x to use gpmc-smsc911x)

fixed by allocating struct platform_device dynamically.

Signed-off-by: Igor Grinberg <grinberg@compulab.co.il>
---
This has been boot tested with nfs root on cm-t35,
and build tested on all other affected boards.

v2:	keep the id field uninitialized (0) on boards with
	only one smsc911x controller (thanks Mike)
