Re: [PATCH 0/24] make atomic_read() behave consistently across all architectures

I looked around a bit by using some command lines and ended up wondering 
if these are equal to busy-wait case (and should be fixed) or not:

./drivers/telephony/ixj.c
6674:   while (atomic_read(&j->DSPWrite) > 0)
6675-           atomic_dec(&j->DSPWrite);

...besides that, there are couple of more similar cases in the same file 
(with braces)...

Generally, ixj.c has several occurrences of couples of atomic write and
atomic read which potentially do not do what the author wanted.
