lx_pipe_state() checks the return value from lx_message_send_atomic()
and breaks the loop only when it's a negative value. However,
lx_message_send_atomic() may return a positive error code (as the
return code from the hardware), and then lx_pipe_state() tries to
compare the uninitialized current_state variable.
Fix this behavior by checking the positive non-zero error code as
well.

Like the other previous changes, this patch for lx6464es takes the
same strategy for converting to nonatomic PCM ops: replacing spinlock
with mutex, converting the irq tasklet to the threaded irq, and
merging the trigger tasklets back to the trigger callback.

Commit be4e6d3c0f ("ALSA: lx6464es: Use standard printk helpers") converted
the custom printk helpers that were used before to standard dev_* functions.
One of the dev_dbg calls had a typo, that was hidden away by an #if 0 .. #endif

Commit f9367f3fbe ("ALSA: lx6464es: Remove unused

of these defines.

The warnings are really harmless but annoying. Since they are only
about debug prints, and it's at most 32bit DMA, let's just cast to
unsigned long.

commit 6175ddf06b optimized the mem*io
functions that have been used to send commands to the device. these
optimizations somehow corrupted the communication with the lx6464es,
that resulted the device to be unusable with kernels after 2.6.33.
this patch emulates the memcpy_*_io functions via a loop to avoid these
problems.
