Don't populate arrays on the stack but make them static. Makes the object code smaller. Also remove temporary variables that have hard coded array sizes and just use ARRAY_SIZE instead and wrap some lines that are wider than 80 chars to clean up some checkpatch warnings.

Module options
--------------
The mwave module takes the following options. Note that these options
are not saved by the BIOS and so do not persist after unload and reload.
mwave_debug=value, where value is bitwise OR of trace flags:
0x0001 mwavedd api tracing
0x0002 smapi api tracing
0x0004 3780i tracing
0x0008 tp3780i tracing
Tracing only occurs if the driver has been compiled with the
MW_TRACE macro #defined (i.e. let ccflags-y := -DMW_TRACE
in the Makefile).
mwave_3780i_irq=5/7/10/11/15
If the dsp irq has not been setup and stored in bios by the
thinkpad configuration utility then this parameter allows the
irq used by the dsp to be configured.
mwave_3780i_io=0x130/0x350/0x0070/0xDB0
If the dsp io range has not been setup and stored in bios by the
thinkpad configuration utility then this parameter allows the
io range used by the dsp to be configured.
mwave_uart_irq=3/4
If the mwave's uart irq has not been setup and stored in bios by the
thinkpad configuration utility then this parameter allows the
irq used by the mwave uart to be configured.
mwave_uart_io=0x3f8/0x2f8/0x3E8/0x2E8
If the uart io range has not been setup and stored in bios by the
thinkpad configuration utility then this parameter allows the
io range used by the mwave uart to be configured.
Example to enable the 3780i DSP using ttyS1 resources:
insmod mwave mwave_3780i_irq=10 mwave_3780i_io=0x0130 mwave_uart_irq=3 mwave_uart_io=0x2f8
Accessing the driver
--------------------
You must also create a node for the driver:
mkdir -p /dev/modems
mknod --mode=660 /dev/modems/mwave c 10 219
