The logic there is too complex and it looks like an inifite
loop.
So, simplify the logic and implement it as a for loop.
This gets rid of the following checkpatch.pl warnings:

Use pr_foo() where there's a direct replacement. For debug, use
custom-made macros, for now, as there are 3 different debug levels.
We should get rid of those some day, specially since several such
macros can be just removed, as Kernel trace would provide about
the same output.
This gets rid of some checkpatch errors:

As warned by smatch:
drivers/media/dvb-frontends/lgdt3306a.c:1354 log10_x1000() error: buffer overflow 'valx_x10' 14 <= 14
drivers/media/dvb-frontends/lgdt3306a.c:1355 log10_x1000() error: buffer overflow 'log10x_x1000' 14 <= 14
There's a potential of returning a value out of the buffer. Fix it.
While here, remove the ugly braced block.

While this is not a mandatory rule at the CodingStyle, we prefer
hexadecimal values in lowercase. Currently, there's a mix of lowercase
and uppercase ons at lgdt3306a. So, convert all to lowercase with this
small script:
perl -ne 'if (m,0x([\dA-F]+),) { $o=$1; $n=lc $1; s,0x($o),0x$n, } print $_'
