Changes since v2:
 
 * Remove change in qcom_geni_serial.c in the last commmit and replace
   it with a comment instead
 * Whitespace fix

Changes since v1:

 * Style fix

-----------------------

Hi,

I had a use for a devm realloc_array in a separate change, so I've
added one and updated all the obvious existing uses of it that I could
find. This is basically a copy paste of the one in slab.h

Applies to v6.3-rc3

Thanks
James

Hi Greg,

Is it possible to take this one? Or at least the first commit?

Thanks

It's the middle of the merge window, no one can take anything new,
sorry.  Please wait for -rc1 to come out and then resend.
