So all of those pdata structs come from kzalloc() so you don't really
have to assign to 0 - simply kill the line.

That part went into drivers/edac/fsl_ddr_edac.c which is only the
freescale memory controller being shared between ARM and PPC, see

http://git.kernel.org/cgit/linux/kernel/git/bp/bp.git/log/?h=for-next

But that shouldn't change the issue wrt ->irq as now it is implicitly 0.

IOW, you can drop this hunk.

Please send v2 against the above branch or linux-next.

Thanks.
