Driver code uses custom return values (often positive) to signal error
condition instead of using standard kernel error codes.
Replace custom return values with standard kernel error codes.

This patch removes multiple assignments by factorizing them.
This was done with Coccinelle for the if branch. For the else part
the change was done manually since Coccinelle only detects constants.
Braces were also added to the else part to remove the checkpatch
warning, "braces should be on all arms of if-else statements".

Using typedef for a structure type and upper case struct names is not
suggested in Linux kernel coding style guidelines. Hence, occurences
of typedefs have been removed and struct names converted to lowercase
in the file. Grep was also used to ensure that all occurence of the
typedefs have been removed. The module compiles without any warnings
or errors.

This moves call to spk_stop_serial_interrupt() function out of synth_release()
and into release() method of specific spk_synth instances. This is because
the spk_stop_serial_interrupt() call is specific to current serial i/o
implementation. Moving it into each synth's release() method gives the
decision of calling spk_stop_serial_interrupt() to that synth.

This patch adds spk_io_ops struct which contain those methods whose job is to
communicate with synth device. Currently, all comms with external synth
device use raw serial i/o. The idea is to group all methods which do the
actual communication with external device into this new struct. Then migrating
a serial-based synth over to an alternative to raw serial i/o will mean
swapping serial spk_io_ops instance with the io_ops instance of the new
method, making the migration simpler.
At the moment, this struct only contains one method, synth_out but more will
be added in future when migrating synths which require input functionality.
Also at the moment, synth_out method has one implementation which uses
serial i/o. Plan is to add an alternative.

These two functions are always called from a context where spk_synth instance
