Subject: [PATCH-2.4] arm: incorrect use of "&&" instead of "&"

Hi Russell,

I'm about to merge this fix into 2.4. It's already been fixed in 2.6.
Do you have any objection ?

BTW, I have two email addresses for you, the one in the MAINTAINERS file
and the one you use on LKML. Which one do you prefer ? Just in case, I've
used both.

Thanks in advance,
Willy

Subject: [PATCH] arm: incorrect use of "&&" instead of "&"

In integrator_init_irq(), the use of "&&" in the following
statement causes all interrupts to be marked valid regardless
of INTEGRATOR_SC_VALID_INT, as long as it's non-zero :

     if (((1 << i) && INTEGRATOR_SC_VALID_INT) != 0)

Obvious fix is to replace it with "&". This was already fixed
in 2.6.
