Subject: [RESEND, PATCH] Fix section for sa11xx-uda1341 platform driver

Don't use __init but __devinit to define probe function.  A pointer to
sa11xx_uda1341_probe is passed to the core via platform_driver_register and
so the function must not disappear after the module is loaded.  Using __init
and having HOTPLUG=y and SND_SA11XX_UDA1341=m the following probably oopses:

	echo -n sa11xx_uda1341.1 > /sys/bus/platform/driver/sa11xx_uda1341/unbind
	echo -n sa11xx_uda1341.1 > /sys/bus/platform/driver/sa11xx_uda1341/bind

Hello,

uups, I forgot to add the right cc:.  Sorry.

@Andrew,  I have a few more patches of this type pending.  Is it OK for
you if they go via you?  This would ease the process a bit for me.

Uwe
