Subject: [ARM] Use unsigned long not u32 in atomic_cmpxchg
X-Git-Tag: firefly_0821_release~39895^2~8
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=49ee57a3295a227b6a02785f75ccd521e493e983;p=firefly-linux-kernel-4.4.55.git

[ARM] Use unsigned long not u32 in atomic_cmpxchg

Since atomic.h does not include types.h, u32 may not be defined.
Since atomics are supposed to work on unsigned long quantities,
use unsigned long instead.
