Subject: [PATCH 1/9][v2] mISDN: use NULL pointer instead of plain integer
Fix more than 100 (all remaining in mISDN) sparse warnings:
drivers/isdn/hardware/mISDN/hfcmulti.c:***:**: warning: Using plain integer as NULL pointer
drivers/isdn/mISDN/dsp_tones.c:***:**: warning: Using plain integer as NULL pointer
drivers/isdn/mISDN/dsp_pipeline.c:***:**: warning: Using plain integer as NULL pointer
