5dac9f8dc2 ALSA: pci: lx6464es: fix a debug loop
This loop accidentally reuses the "i" iterator for both the inside and
the outside loop.  The value of MAX_STREAM_BUFFER is 5.  I believe that
chip->rmh.stat_len is in the 2-12 range.  If the value of .stat_len is
4 or more then it will loop exactly one time, but if it's less then it
is a forever loop.

It looks like it was supposed to combined into one loop where
conditions are checked.

Sparse throws the following warning:

evaluates to false

This comparison and error message make no sense, let's remove them.

a19c921fca ALSA: lx646es: Fix possible uninitialized variable reference
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.

a29878553a ALSA: lx6464es - fix device communication via command bus
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.
