[patch v3 1/2] video/saa7134: change dprintk() to i2cdprintk()

[Dan Carpenter <error27@gmail.com>]

The problem is that dprintk() dereferences "dev" which is null here.
The i2cdprintk() uses "ir" so that's OK.

v2: Jean Delvare suggested that I use i2cdprintk() instead of modifying
dprintk().
v3: V2 had a bonus cleanup that I removed from v3
