[PATCH 1/3] arch/mips/txx9/generic: init dynamic bin_attribute structures

[Wolfram Sang]

Commit 6992f5334995af474c2b58d010d08bc597f0f2fe introduced this requirement.
Found with coccinelle, but fixed manually. Compile tested on X86 where
possible.

Regarding all 3 - it looks like these dynamically alocated attributes
could be converted to statically allocated ones. I'd recommend doing
that instead (in fact, I posted patch for the firmware_class couple days
ago).

I agree for the firmware-patch. Regarding the MIPS one, 'size' might differ and
'private' will differ per instance. Regarding the RTC driver, 'size' might also
differ. I don't know if somebody really wants two RTCs or the SRAM for MIPS can
be instantiated more than once. Unless somebody with actual hardware jumps in,
I'd say better safe than sorry.

Thanks for the comment!

Ah, right, size... I forgot about it. You are right, making the other 2
static is not an option.

On the txx9 platform you've posted the patch for additional RTCs or SRAMs
would not normally be expected.  On other platforms such as IP27 there
would be one per node that is potencially very many.
